The following is a summary of counter usage and manipulations available in LaTex.
The following commands have a counter associated with it:
- part
- chapter
- section
- subsection
- subsubsection
- paragraph
- subparagraph
- page
- equation
- figure
- table
- footnote
- mpfootnote
- enumi
- enumii
- enumiii
- enumiv
You have several possibilities to manipulate counters in LaTex:
\addtocounter {counter} {value}increments the specified counter by the value.\newcounter {newcounter} [oldcounter]defines a new counter. Option ‘oldcounter’ is to link ‘newcounter’ to ‘oldcounter’.\setcounter {counter} {value}sets the counter to have the specified value.\usecounter{counter}used as the second argument of the list environment to number list items (see list command).\value {counter}produces the value of the counter and is useful for doing arithmetic with counters.\renewcommand {cmd} [args] [opt] {def}general command to define/redefine new commands.
Counter values can be printed in different formats such as:
\alphor\Alph {counter}for letters (a…z or A…Z) .\arabic {counter}for arabic numbers (1…9).\fnsymbol {counter}printing various symbols: asterisk, dagger, double dagger, section mark, paragraph mark, double vertical lines, double asterisk, double daggers, double double daggers. The value of counters must be between 1 and 9.\romanor\Roman {counter}for roman numerals (I,II,III,IV,V,…,X,etc.)
Do you know of a way of defining newcounter such that I can have a separate macro that prints out my own heading? eg.
I want to use \creatTask{Develop a new Algorithm},
to expand into \textbf{TASK 1 — Develop a new Algorithm}.
Thank you.
Hi!
Try the code below, I think it solves your problem. I am using a newcommand “\createTask” which you call each time you want to create a new task. You can modify the new command to your needs, e.g. add the dash, etc.
\documentclass{article} \newcounter{taskcounter} \begin{document} \newcommand{\createTask}[1]{ \stepcounter{taskcounter} \bf{TASK \arabic{taskcounter} #1} } \section{My three tasks} \createTask{Your first task} \newline \createTask{Your second task} \newline \createTask{Your third task} \end{document}Thank you Tom!
I have a counter-related question. I’m writing the outline of a document and want the section headings to be called simply “Chapter 1”, “Chapter 2”, etc. However, I need to move things around (i.e. move entire sections up or down) which messes the numbering, and then I have to go a manually change all of the headings. Any suggestions on how can I reference the chapter number without having to use actual numbers?
Hi Felipe,
You can use labels to reference many things including all headings. Just place the label command (\label{label:name}) below the heading and use \ref{label:name} to access the number.
Cheers,
Tom
Fantastic idea! Many thanks!!
Hi, first of all, great blog. Anyway, do you know if there is any command that gets the max value of a counter in a list? Thing is, I need to typeset a list where the label is normally:
P 1 – This and that and that.
P 2 – This and also another thing.
However, if there is only one \item in the list, it should be typeset as:
Paragraph – I’m alone in this list!!
Therefore, when defining the \newenvironment, I will probably need to use, as a condition value for \ifthenelse, some command like \maxvalue{counter}, as in:
\ifthenelse{\maxvalue{counter}=1}{Paragraph - }{P \arabic{counter} -}The question is, of course, is there such a command (maxvalue)? Is it something LaTeX can do?
Thank you very much, I can send you the sources if you want.
David
Don’t know if you still need it, but…
I think the easiest way is to manually label the last item, then in your environment definition check the counter value associated with that label. Not sure though because I’m not that much of an expert, but there is a package called lastpage which counts pages in a similar way. You do have to run latex twice to get the counter right.
Also, it may become problematic if you want several of those environments in your document, but maybe you can fix that by making the label name a variable which is passed as an argument to the environment. Then if you use a different label for each occurence of the environment you should be ok. Not exactly trivial though…
An example of the code in the document body: (don’t know how to do code layout on this blog, sorry about that)
\begin{myenv}{lbl1} \item blabla \item blabla \item \label{lbl1} blabla \end{myenv} \begin{myenv}{lbl2} \item \label{lbl2} blabla \end{myenv}I hope this works for you. I don’t have any experience with creating my own environment so I can’t test it unfortunately.
Thanks for your comment!
For code,
[sourcecode language=”latex”]…
[/sourcecode]should work.
Cheers, Tom.
Hi David,
If I understood your problem correctly, I do not think you can do it the way you propose, as Latex runs through your code sequentially and therefore cannot know the final value of a counter beforehand. Hence there is nothing like \maxvalue{counter}.
You would probably need to do it manually…
Tom
Thank you for your help, I was afraid of that, exactly. I guess I will need to figure out another automatic way of doing that (mixing latex/scripts probably).
Hi,
plz help me!!
How can i link footnote counter to pabe counter?
Thanks.
Hi,
You can use the Latex variable “\thepage” to get the current page as a number.
Look at this post for how to customise header/footer:
http://texblog.wordpress.com/2007/11/07/headerfooter-in-latex-with-fancyhdr/
Hope this solves your problem. If not, let me know.
Hi,
Thanks,
In the above lesson (maybe!) you write
————————————————————————–
\newcounter {newcounter} [oldcounter]defines a new counter. Option āoldcounterā is to link ānewcounterā to āoldcounterā.————————————————————————-
i want create such link (beetwen newcounter and oldcounter).
It means that when the oldcounter is increased the newcounter is set to zero!!
Thanks a lot.
You can try to use \newcommand:
\newcommand{\name}[3]{ %arguments: newcounter, oldcounter, value \addtocounter{#1}{#3} \setcounter{#2}{0} }I am not sure whether this will work, you have to try it yourself.
Good luck:).
Hi again! I almost managed to do what I wanted, using \label and \ref to store a given value in the aux file. Here is what I did:
%%%%%%%%%%%%%%%%%%%%%%%% \newcounter{listnum} \makeatletter \newcommand\firstitem{\@item[ImAlone-]} \makeatother \newenvironment{myenumerate}{ \refstepcounter{listnum} \begin{enumerate} \ifthenelse{\equal{\ref{enum:\arabic{listnum}}}{1}} { \let\item\firstitem \refstepcounter{enumi} }{ \refstepcounter{enumi} } }{ \label{enum:\arabic{listnum}} \end{enumerate} } %%%%%%%%%%%%%%%%%%%%%This is: for each myenumerate env in the text, there will be a correspondent enum:(number) label, and at the end of the processing, those counters will hold, as value, the total number of items in the environment, plus 1.
With 3 myenumerate ‘s, each with 1,4 and 1 numberof \item ‘s, respectively, I get a clean compilation, but:
2.
2.
3.
4.
5.
2.
So, I’m very close, but since I’m a total newbie in LaTeX, there is something simple I can’t realize. Could you help me? Maybe try it?
Thanks a lot.
How to change numbering of figures in a standard Latex article style from Figure 1: to Figure 1.
(i.e., colon to dot after numbers)
Hi Alex,
You can actually customise your caption completely.
To answer your question, you need the package “caption2”:
\usepackage{caption2}Then you renew the “caption label delimiter” through:
\renewcommand{\captionlabeldelim}{.}If you want to have the colon back for whatever reason, just use the command again inside your document with a colon instead of a dot.
This should solve your problem.
Cheers,
Tom
Hi,
I am writing a document with many constants that I want to write $C_i$ with $i=1,2,…$, and such that I can make a reference to a specific constant later. So I tried to define a counter \cte, a command \newcte{label} that prints $C_\thecte$ and labels it with some label, and then another function \usecte{label} that would print the corresponding constant.
I tried:
\newcounter{cte} \newcommand{\newcte}[1]{ \refstepcounter{cte} \label{cte:#1} C_{\thecte} } \newcommand{\usecte}[1]{ C_{\ref{cte:#1}} }But I don’t understand why this does not work. Moreover, I have an annoying problem: when I want to use this syntax in an align environment with a label, I get a multiple labels error…
Thanks in advance if anyone knows how to make this work (the way I tried or any other way!).
Hi Florian,
What you did works perfectly, just that you forgot the dollar signs ($), even though you had them in the text. Here is the corrected code:
\newcounter{cte} \newcommand{\newcte}[1]{ \refstepcounter{cte} \label{cte:#1} $C_{\thecte}$ } \newcommand{\usecte}[1]{ $C_{\ref{cte:#1}}$ }And now you can print what you wanted:
\newcte{bla}->\ref{cte:bla}-> 1Hi,
I’m using “book” as the document class. And I want to link chapters to parts, so whenever I create a new part, the chapter counter is reset to 0. The easiest way to do this would be to just add following code in the preamble:
\newcounter{chapter}[part]Right? But LaTeX always complains that the counter “chapter” has already been defined.
How do I do this efficiently, without having LaTeX complain? Please help. Thanks in advance.
Hi Troy!
The counter is indeed already defined. What you have to do is reset it to zero.
The following line after each “part-command” will do the trick:
\setcounter{chapter}{0}Cheers,
Tom
Thanks a lot. I was searching for this info for long time.
You are welcome! Best, Tom.
Hi Tom,
Thanks for your tip. I tried that, and at the first look, it’s the solution I was looking for. But only at the first look. See, I use PDFTeX. And setting the “chapter” counter to zero whenever I call “part” does the trick visually. This solution would work fine as a print. But my goal is PDF.
The problem is, let’s say I have two parts in my book, with various chapters in each part. Now, in the table of contents in the PDF, if I click on the second chapter of part II, the link doesn’t take me to the second chapter of part II. Instead, it takes me to the second chapter of part I. So internally, setting the “chapter” counter to zero every time part is called up messes with PDFTeX’s linking system.
Is there any way to avoid that? There has to be an elegant solution to this problem without having to program new \chapter or \part, because I want to be able to use my .tex files in other projects as well without having to change anything.
Thanks again. Cheers,
Troy
Hi Troy,
my answer comes probably a bit too late to help you but in case anybody else faces the same problem: Include the following command in your preamble:
\renewcommand*{\theHchapter}{\thepart.\thechapter}Cheers,
PLS
Hi Troy,
I see your point. The books I have seen usually have consecutive chapter numbering even over different parts. I couldn’t find a solution to your problem, sorry!
Cheers,
Tom.
Hi,
thank you for your answer. unfortunately, what does not work is that I cannot use this code inside an environment \begin{align} with a label, because then there is a conflict on the labels…
i have found a trick by using the package smartref, but if anybody has a better solution, I am interested!
hello
I want for my math formula number, first have equation number then have chapter number, e.g.(34-2)
34 is equation number and 2 is chapter number
how can I do this?please guide me
@venus
In Latex, you can always access the counter of a specific environment using \theenvironment, e.g. the equation-environment counter is accessed through
\theequation.Your problem can be solved by redefining the equation counter as follows:
\renewcommand\theequation{\arabic{equation}-\thechapter}Cheers,
Tom
Hi all,
I have the appropriate “example” environment, and its respective ExampleCounter.
I want to be able to continue an “example”, as in:
Example a: xyz
Example b: xyz
Example c: xyz
Example b (continued): xyz
Example d: xyz
My question is:
How do you:
(1) set ExampleCounter = value of ExampleCounter of the (say the) second example (ie. Example b:)
(2) Use the counter to create the example: “Example b (continued):” (i.e. \begin{example}[continued] xyz \end{example}
(3) set ExampleCounter = value it had before step (1) —so that I can continue with the correct example labels…
Thanks in advance,
Erick
Hi Erick,
I couldn’t find a nice answer to your questions (1) and (3).
Concerning question 2, a possible way to do it is the following:
\newcounter{examplecounter} \newenvironment{example}[1]{ \addtocounter{examplecounter}{1} Example \theexamplecounter#1:}{\\}and then
\begin{example}{} xyz \end{example} \begin{example}{ (continued)} xyz \end{example}The disadvantage is, you always have to have the optional argument brackets when using the environment.
For (1) & (3), you can simply add and subtract from your counter:
\begin{example}{}xyz\end{example} \begin{example}{}xyz\end{example} \begin{example}{}xyz\end{example} \addtocounter{examplecounter}{-2} \begin{example}{ (continued)}xyz\end{example} \addtocounter{examplecounter}{1} \begin{example}{}xyz\end{example}This is obviously not dynamic, but I couldn’t think of a better solution for now, sorry.
Cheers,
Tom
hello thnks for your worth help
First of all I wanted to thank Tom for his response. I also wanted to post a possible solution to my questions 1 and 3 that is somewhat more dynamic (although definitively not elegant).
%First we need to save counter before the example that we wish to %continue later (say save its value in the newcounter 'ex') \newcounter{ex} \setcounter{ex}{\value{examplecounter}} %When where we want to continue the example we can load the %saved counter (we need to save the current counter value in the %newcounter temp ---so that we can restore it later) \newcounter{temp} \setcounter{temp}{\value{examplecounter}} \setcounter{examplecounter}{\value{ex}} %We continue the example (as Tom showed) \begin{example}{ (continued)}xyz\end{example} %Finally we restore the counter value \setcounter{examplecounter}{\value{temp}}Erick
hi all
I’m looking to define a new sort of section to my document where i store all my figures. It should be something like when you do \appendices your chapter titles change from Chapter 1,2,3 to Appendix A,B,C
I want this new section at the very end (after appendices, bibliography, etc), and when i type \figures for instance, chapter titles should change to Figures Chapter 1,2,3
What do you think is the best solution for this? And do the figurecounters automatically change too? (so they look like Figure 1.12, 2.34, etc)
I need to print a document in batches of pages. I’d LIKE to do this by creating separate documents for each batch of pages (the batches have different layouts and are printed on different paper so it makes some sense to separate them).
In order to do this, I need to set the starting page of each document. I haven’t had much luck modifying \thepage… it seems to be defined as a macro command somewhere deep in the bowels of TeX.
Any/all help and suggestions are welcome,
thanks.
Sorry… my bad… I found the (very simple) answer moments after posting:

Great, I used:
\newcommand{\listexamples}{List of Examples} \newlistof{examples}{exp}{\listofexamples} \newcommand{\example}[1]{% \refstepcounter{examples} \vspace*{0.2in}\par\noindent\sqrblt\textbf{Example \theexamples. #1} \addcontentsline{exp}{examples} {\protect\numberline{\theexamples}#1}\par}however…
1. If I set example numbers to include chapter, than in the table of contents the example number overlaps with the text (i.e. the numwidth is not properly set).
2. Also, I would like to have an extra space in between the examples from various chapter.
Thanks
Hi! thanks for the great blog! I have a question. I have document with Chapters 1, 2, 3, and sub sections 1.1 1.2…. 2.1, 2.2 … so on.. How do I set a counter for a figure X that belongs to Chapter Y and subsection Z, so that its number will appear as Figure Y.Z.X ?
… and basically same question for tables…
Hi!
What you would need to do is the following.
Define a new counter:
\newcouter{myfigure}and tell Latex how you want your figure counter to look like:
\renewcommand{\thefigure}{\addtocounter{myfigure}{1}\thesection.\themyfigure}%If you want Latex to reset the counter everytime you start a new chapter you need to add this piece of code:
\makeatletter \@addtoreset{myfigure}{chapter} \makeatotherHope this is what you were looking for,
Tom
Thanks a lot!
Tom,
Your last tip can solve Troy C.’ s problem :
To change chapter number each time changing part, add in your preamble
\makeatletter \@addtoreset{chapter}{part} \makeatotherHi,
I am writing a book that contains a certain number of tables and figures.
I would like to include the total number of figures and the total number of tables in the front page.
I was wondering if there is way to do so automatically.
Thanks in advance.
Hi,
Thanks for your question, which was rather tricky to answer :-). The problem is, that you first have to run through the document in order to know the number of figures.
I propose you write a macro with the code given below, so you don’t mess up your tex-file:
1. Open a new text-file and call numberfigure.sty.
2. Copy-paste the code below into the file and save it.
3. Add the
numberfigurepackage to your Latex-document.4. Use
\pageref{NumberFigures}to print the number of figures.I have to admit, the solution is not very nice and I would be happy if someone who is familiar with macros would post a better solution.
Here is the macro code for numberfigure.sty:
\newcounter{myfigure} \setcounter{myfigure}{0} \newcommand{\mycaption}[1]{ \stepcounter{myfigure} \caption{#1}} \def\numberfigures@putlabel{\addtocounter{myfigure}{0}% \immediate\write\@auxout{\string \newlabel{NumberFigures}{{}{\themyfigure}}}% \addtocounter{myfigure}{1}} \AtEndDocument{% \clearpage\numberfigures@putlabel}% \endinputCheers,
Tom
It worked!!! Not only for the tables and figures, but also for a user-defined floating environment as well. Thanks a lot for your prompt help.

Hi,
I’m a little stuck with list numbering. I’m creating a list of assumptions in a paper. However, I would like the assumption counter to reset ONLY when the chapter number changes. In other words, I’d like the text to read:
Chapter 1, Section 1
~
Assumption 1.1
Assumption 1.2
~
Chapter 1, Section 2
~
Assumption 1.3
Assumption 1.4
~
Chapter 2, Section 1
~
Assumption 2.1
~
Currently though, the assumption counter resets every time I call the assumption environment. Here’s my code for the environment:
\newcounter{assump} \newenvironment{assumption} {\begin{list}{Assumption \arabic{chapter}.\arabic{assump}:} {\usecounter{assump}}} {\end{list}}I’ve tried adding “[chapter]” to the end of the counter definition, but it still doesn’t ensure that the counter is reset only when the chapter changes. Any ideas? Thanks!
Ah, nevermind, I figured out a way around it. I added a new counter using
\newcounter{assumpt}[chapter]which keeps the total of the assumptions in a chapter. Then I changed the last two lines of the above code to:
{\usecounter{assump}}\addtocounter{assump}{\value{assumpt}}} {\end{list}\setcounter{assumpt}{\value{assump}}}Thanks though!

Dear Tom,
From the blog, it seems that you are the guy who can help me..:) I need to number my figures in following 1,2a,2b,3,4….. way. As I understood, I have to use
\newcouter, this kind of stuff. But I could not figure out how to do it properly. Here is my code :\begin{figure}[h!] \centering \includegraphics[clip=true,width=8cm]{vac_tim_5.eps} \caption{Time dependence of the number of defects.} \label{fig2} \end{figure} \begin{figure}[h!] \centering \includegraphics[clip=true,width=8cm]{vac_tim_6.eps} \caption{Time dependence of the number of defects. The curves are averages of twenty irradiations.} \label{fig3} \end{figure}I would like to put the label as 2a and 2b then again 3, 4….
please help.

Hello!
I suppose the two figures (a) and (b) belong together and should be displayed together? Please have a look at the
subfigpackage, which is a much cleaner way to generate sub-figures and automatically numbers the figures the way you want.Here is a post I wrote some time ago about
subfigincluding sample code. You may also want to have a look at the package documentation.Let me know if you have any more questions.
Best, Tom.
Hello,
Thanks a lot for you reply. These documents will help me for sure. But, I need to make two different figures with two different captions and labels, (a) and (b) don’t belong together. Some complete different figures in different places of the article like 1,2,3,4,5.. except I want to make it like 1,2a,2b,3,4,5… one figure after another figure, with there own caption. By doing normal way I can make figures and Latex number them automatically Fig1, Fig2, Fig3…. But I want to have Fig1, Fig2(a), Fig2(b), Fig3….
I guess, this time I made it clear..:)
thanks in advance..
cheers
Ullah
Hey Ullah,
I put together some code that will modify
\thefigurethe way you need it. Put it into your preamble.\let\thefigureold\thefigure \newcounter{mysubfig} \newcounter{const} \newcommand{\modfig}{ \setcounter{mysubfig}{1} \setcounter{const}{\thefigure} \addtocounter{const}{1} \renewcommand{\thefigure}{\theconst\alph{mysubfig}\addtocounter{mysubfig}{1}}} \newcommand{\resfig}{ \setcounter{figure}{\theconst} \let\thefigure\thefigureold}The only thing you have to do now is to call
\modfigto start the subfigure numbering and\resfigto stop it and continue normal figure numbering.Best, Tom.
Hi,
Thanks a lot. I feel there is some bug in the code or may be I am too novice to understand.:( When I call \modfig and \resfig in the first figure it gives 1a number. But when I call at the beginning of my second figure and close at the end of third figure, it gives 2b and 2d. where I was expecting 2a and 2b. But I found another blog, and I fixed it now..in the following way..
In to preamble:
\usepackage{subfigure} \newcounter{subfigure1}Then at the beginning of the 2nd figure
\renewcommand{\thefigure}{\arabic{figure}\alph{subfigure1}} \setcounter{subfigure1}{1} \begin{figure}[htb] ......then beginning of the third figure
\addtocounter{figure}{-1} \addtocounter{subfigure1}{1} \begin{figure}[h!] ......and at the end to continue normal figure numbering.
\renewcommand{\thefigure}{\arabic{figure}}this gives me 1,2a,2b,3,4,5 …..
regards
Ullah
That looks good and makes sense in case you use it once only.
By the way, you don’t need to load the
subfigurepackage, it’s not needed here.Best, Tom.

(Moved here by Tom.)
Is there a simple way to have counters (e.g., equations) in a document pick up where the previous document left off? Obviously, I can always manually set the counter at the beginning of the new doc, but discovery of the xr package got me to thinking that perhaps there’s a similarly automated way to do this.
Thanks!

Hey Alec,
I moved your comment to this more suitable post. So here is my response. I tried quite a few things and I could not find a simple way to use counters across multiple documents. You could give the
zrefpackage a try (documentation).In some cases,
includemay do the job. You can compile a list of individual tex-files once, generating all the counters, page-numbers and labels correctly. They will be stored in meta-files (e.g. *.aux). Next, you compile only a subset (one or more) usingincludeonly:\documentclass[11pt]{article} \includeonly{file2} \begin{document} \include{file1} \include{file2} \include{file3} \end{document}Best, Tom.
Thanks so much! I’ll give it a try.
best,
Alec
Sure, good luck :-). Tom.
Hi,
I was curious to know that is there any possibility that I manage to have two different kind of numbering for figures. For example I have a picture of a table and I want to have a separate numbering for figures of tabels!
Sincerely,
Hey,
Have a look at the
trivfloatpackage. Also, here is a code example in the comments of this previous post on defining your own list of….Let me know if you have any problems.
Best, Tom.
Hey,
Thank you for usefull information.
I see that you are pro in latex docs, so I would like to know if there is a possibility to show the equation counter on a different side of a document, because it is on the right side of a page by default.
I am looking forward to hearing from you.
Hey!
You can use the documentclass option
leqnofor equation numbering on the left side. Here is an example:\documentclass[12pt, leqno]{article} \begin{document} \begin{eqnarray} f_1(x) & = & a_1+b_1x+c_1x^2\\ f_2(x) & = & a_2+b_2x+c_2x^2 \end{eqnarray} \end{document}Best, Tom.
Works. Thank you very much.
You are welcome. Tom.
Is there a way to count the number of entries in a bib file? I am writing my CV and wished to have something like:
Oral Presentations (3):
Reference1
Reference2
Reference3
Poster presentations (4)
Reference 4
Reference5
Reference6
Reference7
What I want is to print the numbers inside the parentheses (oral presentations are in oral.bib and poster presentations are in poster.bib)
Thanks
Hi Filipe,
Here is a minimal working example. It’s certainly not the most efficient way to do it, but it works. You’ll have to run “bibtex poster” and “bibtex oral”. Best, Tom.
\documentclass[11pt]{article} \usepackage{multibib, totcount} \newtotcounter{oralcount} \newtotcounter{postercount} \newcites{poster,oral}{% Poster Presentations (\protect\total{postercount}),% Oral Presentations (\protect\total{oralcount})} \def\oldciteoral{} \let\oldciteoral=\citeoral \def\citeoral{\stepcounter{oralcount}\oldciteoral} \def\oldciteposter{} \let\oldciteposter=\citeposter \def\citeposter{\stepcounter{postercount}\oldciteposter} \begin{document} First poster reference: \citeposter{posterref2012} Second poster reference: \citeposter{posterref2011} First oral reference: \citeoral{oralref2012} \bibliographystyleposter{plain} \bibliographyposter{poster} \bibliographystyleoral{plain} \bibliographyoral{oral} \end{document}What if I use \nocite? I only get 0’s… I wish to count the entries in the bib file. is that possible?
Hi Filipe,
The command
nociteis tricky. Try the biblatex package which offers great flexibility. Furhtermore, you may find these answers to a somewhat related question useful.Best, Tom.
Actually I did change every \cite… to \nocite… and it works perfectly. The only thing I which it could do additionally would be instead of having to add every reference by by hand using the \nociteoral{ref1}\nociteoral{ref2}\nociteposter{ref3}… i could just \nociteoral{*}\nociteposter{*} but sadly it won’t work…
Thanks for the follow-up. Indeed, according to the documentation, the star as a placeholder for all references in a bib-file was not implemented. Best,Tom.
Great blog!! This may not have a solution (possibly, due to it’s narrow application base):
I am writing up mathematical models in LaTeX [i.e. a lot of equations] and then coding up models in Java/C++/C algorithm for implementation. To keep track of which part of code belongs to which equation, I comment the code with the related equation number [company policy!!]… this works when document is growing from the bottom. However, I now have to go back and add sections here and there in document, which screws up numbering and my code comments. The only solution I can see to dynamically link my equation numbers to my code is the following:
1) Label each equation (100s of ’em) inside LaTeX and in relevant code
2) Utilize *.aux file + script to extract labels and equation number
3) Run code through another script to append new eqn number to label
But is there some better way to extract equation numbering without labeling everything in LaTeX? From what I can tell, only if I label equations do they appear in *.aux file.
Or for short-term solution, is there a way to keep old equations numbers and just increment LaTeX counter for every additional equation — to avoid overwriting old equation numbering?
Any ideas? Thanks in advance!!
Hi Mads,
Thanks for your interesting question. I don’t know the exact policy of your company on identifiers. In case you can use any identifier format (e.g. no consecutive numbering, etc.), I suggest using the equation label, since it remains the same when the document is changed. Using the showlabels package, you can print the label into the margins for example.
Since you have so many equations, you might also find the catchfilebetweentags package useful. It lets you store chunks of code in a text file and load them. I’m not sure if this is useful, but with this package you might even be able to automatically fetch the code of the equation implementation and add it to the LaTeX document using listings.
In case you prefer using the actual equation numbers, say because you have a list of equations, what comes to my mind is use any of the tocloft commands to change the entries and extend it to write the equation numbers to a file that is easily parseable.
Hope you find my thoughts useful. I’m sure you’ll find a solution that suffices the requirements and is convenient.
Cheers, Tom.
Is it necessary to be a code number or could it be a code name? If so, it would be rather easy just to set names… Can you do that? (That must be exhausting do, to name hundreds of equations…) I can’t think of any other way to do it besides that outer script you mentioned.
Hi.
Is there a way to compute the actual (or physical) page count (current and possibly last)?
Or, otherwise phrased, is there a {globalpage} counter that is indifferent to anything the user does to the {page} counter?
To clarify the question suppose you reset counter{page} as you go (e.g., preface in roman+body in arabic, as found in many texts, or you use the \include{} command and skip some sections).
Suppose now that for typographical reasons you would like to understand whether the last page is a multiple of 4 or not (as to insert extra blank pages, for example). If the page counter is never reset, that’s easy. But if the page counter does get reset, this becomes a problem.
Hi Oskar,
An interesting question. Yes, there is a way to determine the absolute number of pages using the zref package. Here is how:
\documentclass[11pt]{article} \usepackage[user, lastpage, abspage]{zref} \usepackage{blindtext} \pagestyle{plain} \begin{document} \pagenumbering {roman} \tableofcontents \clearpage \section{Test} \pagenumbering {arabic} Last page number: \zpageref{LastPage}; absolute page number: \zref[abspage]{LastPage}. \end{document}In this blog, I found that I can change my page numbering from arabic to roman. But in my thesis, cover page must be without page number then few pages in roman page numbers and then rest of pages english numbers.
http://ashishrevar.com/2010/09/latex-redefine-numbering-in-figure-caption/
This page is only useful to change the number style but how to unset page numbers in cover page?
Hi Disha,
Try the following to switch off page numbering for the first few pages.
\documentclass[11pt]{report} \usepackage{blindtext} \begin{document} \pagenumbering{gobble} \tableofcontents \clearpage \pagenumbering{arabic} \chapter{First} \Blindtext \end{document}I am using \begin{multline}…\end{multline} for some very long equations that span more than 60 lines. I would like to refer to specific lines in such equations. I have defined a counter, incremented it, and print a small number after each line. To avoid manual referencing of the lines I would like to refer to, I have attempted to use the \label command along with \refstepcounter. While this works fine outside the equation environment, it does not work within the multline. Any suggestions for this unusual application?
Hi Casey!
Thanks for this question. In fact, you could just use align. See the example below.
\documentclass[11pt]{article} \usepackage{amsmath} \begin{document} \begin{align} y_1&=a_1x_1+b_1 \label{eqn:one} \\ y_2&=a_2x_2+b_2 \nonumber \\ % omit number y_3&=a_3x_3+b_3 \label{eqn:three} \end{align} See \ref{eqn:one} and \ref{eqn:three}. \end{document}Hi Tom,
Align will not do the job because the 60+ line expression is indeed one equation and thus needs to be numbered along with the other equations in the document consistently. What I need to do is to refer to individual lines within this one equation. Thus I needed embedded numbering that can be referenced. Sorry for not being more clear.
Hi Casey,
Please provide a minimal working example and I’ll try to help you with the problem.
Tom.
\documentclass{article} \usepackage{amsmath} %.....Tiny line numbering for long equations \newcounter{eqnline}[equation] \newcommand{\eln}{\stepcounter{eqnline}\hfill \hbox{\tiny{\theeqnline}}} \begin{document} Here is a minimal example: \begin{multline} a = b + \dots \eln \\ c + d \dots \eln \\ e + f \dots \eln \\ \dots+g + h \dots \end{multline} The real application has a single equation that spans more than 60 full lines, and I would like to be able to refer to the line numbers using a label construct within the equation, which I number using a defined counter as shown above. \end{document}Thanks for the code! The code below works (apart from hyperref, which I didn’t test). I took the idea from here. HTH, Tom.
\documentclass{article} \usepackage{amsmath,refcount,makerobust} \newcounter{eqnline} \newcounter{refeqc} \let\textlabel\label \newcommand{\eln}{% \begingroup \refstepcounter{eqnline}\mylabel{\theeqnline}\hfill \hbox{\tiny{\theeqnline}}% \endgroup} \newcommand{\mylabel}[1]{\textlabel{lnl:#1}} \newcommand{\eqqref}[1]{% \setcounterref{refeqc}{#1}% Line $(\arabic{refeqc})$} \begin{document} \begin{multline}\label{eqn:dummy} a = b + \dots \eln \\ c + d \dots \eln \\ e + f \dots \eln \\ \dots+g + h \dots \end{multline} Referencing the equation: \ref{eqn:dummy} Referencing lines: \eqqref{lnl:2} \end{document}Thanks Tom! This solution will work.
Hi Tom,
Using documentclass{book} I have \setcounter{secnumdepth}{3} before \mainmatter. For one of the chapters this setting is one too deep, so I want to change it for that chapter only. I’ve tried resetting within the chapter, but to no avail. Do you have a solution to this.
Thanks a lot, in anticipation,
PaulT.
Hi Tom,
I left my previous post when frustrated after spending some time googling but failing to find a solution. However, I got the google question right today and now have the solution, which is simple.
Cheers,
PaulT.
Thanks for getting back to me. Would you mind to post the solution that worked for you? Thanks, Tom.
Hi Tom,
The solution was to use the asterisk answer—i.e. include an asterisk in the section heading: e.g.
\subsubsection*{Arguments}. This prevents the section heading being listed in the table of contents (toc).Cheers,
PaulT.
Paul, thanks for posting the solution, appreciate it! Best, Tom
Hello š
I am writing my Master’s Thesis and I have a big big problem: I have to put 87 figures, two for page, so I am using the \subfloat command.
When I compile I get the error Counter too large. How can I solve it? My figures are labeled as A, B, C…..what’s the right way to continue labelling them AA, BB, CC… and so on?
Thank you in advance,
Fede
I think with the alphalph package you should be able to fix your problem. Let me know if you can’t get it to work. In that case, please provide a minimal working example.
Best, Tom
Hello,
I want to use additional counters for page number in appendices, so that the main numbering (bottom) goes from beginning to the end of the document, and header (if the page is in appendix) must contain something like “Appendix 1. Page X of XXX” where XXX is the number of pages in appendix. Can I do it with custom counters? Thanks.
Hi there,
Thanks for your question. The lastpage package does what you are looking for. I wrote a short post about it some time ago.
HTH,
Tom
Hello,
How do i stop counter? I need to stop counting pages at the appendices i have following;
\setcounter{page}{1} \fancyfoot[C]{Page \thepage \ of XXX} \pagenumbering{arabic} %use arabic page numbering in the mainmatter \input{sections/cp1-introduction.tex} \input{sections/cp2-problem_formulation_and__description.tex} \input{sections/cp3-methodology___Theory.tex} \input{sections/cp4-analysis.tex} \input{sections/cp8-discussion.tex} \input{sections/cp9-conclusion.tex} %% I NEED TO STOP COUNTING PAGES FROM HERE%% \printbibliography[heading=bibintoc] \label{bib:mybiblio} \appendix \addcontentsline{toc}{chapter}{Appendix} \input{sections/appAname.tex} \input{sections/appBname.tex} \input{sections/appCname.tex} \end{document}Best Wishes and thanks in advance
Hi Nils,
I assume you use the lastpage package as described in this post. The easiest solution would be to place a
labelon the last page (before the appendices) and then use\pagerefto print that page number.Best, Tom
\documentclass{report} \usepackage[toc,page]{appendix} \usepackage{blindtext, fancyhdr} \pagestyle{fancy} \fancyfoot[C]{{\thepage} of \pageref{LastContentPage}} \begin{document} \tableofcontents \blinddocument \label{LastContentPage} \appendix \chapter{Appendix} \blinddocument \end{appendices} \end{document}Hello Tom,
Thank you for the awesome blog.
I am new to Latex environment. I looked at your response (11/9/2011) related to custom
toc. Is there a special package that I need to download from CTAN ? Currently in list of tables I have VIII.1, VIII.2 etc that needs to changed to A2.1, A2.2 etc.
2. How do i setup margins 1 Ā½ā on the LEFT and 1ā on the OTHER THREE SIDES for the entire document ?
Thank you.
Hi Joe,
1. To change the way a counter value is printed, you won’t need a package.
\renewcommand*{\thechapter}{A\arabic{chapter}.\arabic{section}}2. Use the geometry package to set the margins globally.
\usepackage[top=1in,bottom=1in,right=1in,left=1.5in]{geometry}HTH,
Tom
