Source code in LaTeX

If you want to include source code in LaTeX, you can of course use the standard verbatim environment. There are however many advantages to refer to the actual source file on disk instead of copying its contents into your LaTeX document. Referring to a file on disk can be achieved by using the moreverb package.

I use the following commands:

\usepackage{moreverb}\def\verbatimtabsize{4\relax} 

to include the package and to set the amount of white space for tab characters to 4 (default is 8). Next define

\newcommand{\listscript}[1]{{\textbf{#1}\footnotesize\verbatimtabinput{#1}}}

to have a new command for including e.g. Matlab scripts. Use it as

\listscript{cp19.m}

to have the file cp19.m in your document.
