m-code to LaTeX converter

This m-file (with GUI) converts m-code into a tex-file for including in a LaTeX-document.

Description

This file lets you very easy INCLUDE COLORED M-CODE in your LaTeX-file.

After you run this m-file "m2tex.m" and inlcude the output tex-file in your LaTeX document, you will experience NO DIFFERENCE IN THE APPEARANCE to the look of the m-code in the Matlab Editor. (except for the apostrophs)

There are SEVERAL WAYS TO EXECUTE the program.
1. Run the file by pressing F5 oder click the "Run" button in the Matlab Editor, while the m2tex.m file is open or type "m2tex" in the Command Window.
==> The program will open the GUI and the rest goes from there.
2. Call the program from the Command Window or another m-file with at least one option. The order of the options is not important. For example:

m2tex('num','C:\Programme\MATLAB\work\testfile.m','C:\latex_documents\testfile.tex')
m2tex('testfile.m','testoutputfile.tex', 'no_num','bwc')

There are ONLY TWO STEPS necessary to do to include your code:
1. Run "m2tex.m" (with the desired m-file to include).
2. Insert the code into your main LaTeX-document by adding the whole "filename.tex"-file with \include{filename} or \input{filename}.

For Example:
\usepackage{fancyvrb}
\usepackage{color}
...
\begin{singlespace} % only optional % you need \usepackage{setspace}
\footnotesize
\input{outputfile} % output from "m2tex.m", but without the extension ".tex"
\end{singlespace} % for changing your linespacing
\normalsize

Features:
 - recognizes all keywords, strings and comments
 - recognizes all indents and tabs
 - recognizes cell titles
 - writes all recognized objects correct in a tex-file
 - uses original Matlab colors
 - the font looks almost the same as in Matlab Editor
 - tex-file is saved using fontencoding "UTF-8", so that German Umlauts will be written correct
 - option for numbered code lines ('num' or 'no_num')
 - recognizes a linebreak, but only with a leading space character, i.e. " ..." and only once in a line
 - option for input- and output-file (*.m respectively *.tex-file)
 - execution via GUI or command line
-----------------------------------------------------------------
The conversion of the linebreak works only, if it is once in a line, because the command "regexprep" (code line: 1385) won't work, if you are looking for a string with three dots: '...'

--> If anyone knows why or a solution around the problem, please tell me! thx

• MATLAB release: MATLAB 7.5 (R2007b)
• Other requirements: LaTeX packages: - fancyvrb - color
• Other Files: license.txt, ; m2tex.m

Very useful and it works at the first time! I got a small error with an equation with 2 transposes in the same line (e.g. : G=P*C'/(C*P*C'+R)). The parser has interpreted the code between both transposes (') as a string. But it's minor. Good job, thanks!

Well done. Really good work. Thanx!

A single problem I have come across:
"if, then, else" only recognized when they are in separate lines. But I'm not so sure what was the problem in my case. I changed it from
     if xx==1; do_this_fcn; else do_that_fcn; end
to
   if xx==1
      do_this_fcn;
   else
      do_that_fcn;
   end
and it worked.

For future versions:
additional input options for 'inputfilename', 'outputfilename' (which would include the directory) and which would help to automatize your script updating routines in a latex based protocol.

Nice work, but I still have some problems with it:
1. The transpose is still considered a string in the following case:
% .*(comp2) and .*(comp4) are colored as strings.
logical((comp1)’.*(~comp2)’.*(comp3)’.*(comp4)’.*(comp5)’);

2. When I use sprintf, then the everything after %s is colored as a string.
handles.(tag) = struct(...
’button’, eval(sprintf(’handles.%s’,tag)),...
’checkbox’, eval(sprintf(’handles.%s_check’,tag)),...
’time’, eval(sprintf(’handles.edit_%s_Time’,tag)),...
’initial’, eval(sprintf(’handles.edit_%s_Initial’,tag)),...
’final’, eval(sprintf(’handles.edit_%s_Final’,tag)),...
’gototag’, tag,...
’path’, path_steps_faults{i});

3. The gui doesn't seem to work. I don't know if anybody else had the same problem, but each button gives the same error:
>> m2tex
??? Error using ==> waitfor
Undefined function or method 'm2tex_gui_app' for input arguments of type 'struct'.
 
??? Error using ==> waitfor
Error while evaluating uicontrol Callback

I hope you can resolve these problems.

another problem that I've just encountered:
error(’The tag ’’%s’’ is not correct.’,boxtag);
% the ",box" is black while "tag);" is blue.
