Goal--Insert Matlab code into LyX

Insert Matlab code into LyX with keywords, comments, etc. in different colors/fonts

Solution

The attached zip file contains a function called matlab2tex.m Execute this function in Matlab giving the full path to an m-file (of course, use the actual path on your system) matlab2tex('C:\MatlabFiles\Lyx\matlab2tex.m'); this creates a TeX file, C:\MatlabFiles\Lyx\matlab2tex.tex

In your LyX document, paste the following into the Preamble
   \usepackage{alltt}
   \usepackage{color}
   \definecolor{string}{rgb}{0.7,0.0,0.0}
   \definecolor{comment}{rgb}{0.13,0.54,0.13}
   \definecolor{keyword}{rgb}{0.0,0.0,1.0}

In LyX, open an ERT box

 Click in the box and do Insert|file|plain TeX and browse to the TeX file 

This will insert the TeX code for the Matlab source

Files

download the zip file at http://lyx.475766.n2.nabble.com/file/n2865240/matlab2tex.zip matlab2tex.zip (or at ftp.lyx.org).

This contains the Matlab code and a sample LyX document and a ps of the result.

Installation

Extract the files in the zip and extract the included highlight.zip into a location on your Matlab path

Example

See the example in the zip file.

Hi! When i try this tool i get this result:

>> matlab2tex('my_file.m')
??? Error using ==> fprintf
Invalid file identifier.  Use fopen to generate a valid file
identifier.

Error in ==> highlight>write_highlighted_code at 126
	fprintf(outfid,out_format.pre_start);

Error in ==> highlight at 110
write_highlighted_code(mfid,outfid,opt)

Error in ==> matlab2tex at 57
highlight(mfile,opt,fid);

Any ideas what this could mean? I'm using Matlab R2010a for linux on Ubuntu 10.10!!!Copyright

I am using Windows 7 under VirtualBox on debian testing and I found the same problem. In my case, when the function fileparts called by matlab2tex was executed, it returned a void string for pathstr and the variable texname which points to the output file becomes '/my_file.tex' instead of 'my_file.tex'.

To fix it, I replaced the lines :

pathfull = [pathstr filesep];

mfile_name_with_path = [pathfull name]; % no extension

mfile_name = [name ext];

    % create a file pointer as input to highlight

texname = [pathfull name '.tex'];

by the line :

texname = fullfile(pathstr,[name '.tex' versn]);

Open source. Use for any application.

Select Insert > Program Listing. Then type the program. To get colors and control many aspects of the listing format, go to Document > Settings... > LaTeX Preamble and copy there something like:

\usepackage{color}
\definecolor{hellgelb}{rgb}{1,1,0.85}
\definecolor{colKeys}{rgb}{0,0,1}
\definecolor{colIdentifier}{rgb}{0,0,0}
\definecolor{colComments}{rgb}{1,0,0}
\definecolor{colString}{rgb}{0,0.5,0}
\lstset{%
    language=Matlab,%
    float=hbp,%
    basicstyle=\footnotesize\ttfamily,%
    identifierstyle=\color{colIdentifier},%
    keywordstyle=\color{colKeys},%
    stringstyle=\color{colString},%
    commentstyle=\itshape\color{colComments},%
    columns=fixed,
    tabsize=4,%
    frame=single,%
    framerule=1pt,
    extendedchars=true,%
    showspaces=false,%
    showstringspaces=false,%
    numbers=left,%
    numberstyle=\tiny\ttfamily,%
    numbersep=1em,%
    breaklines=true,%
    breakindent=10pt,%
    backgroundcolor=\color{hellgelb},%
    breakautoindent=true,%
    captionpos=t,%
    xleftmargin=1em,%
    xrightmargin=\fboxsep%

}

Next go in Lyx to Insert --> File --> Subdocument. Type:Program Listing You're done.
