How can I include MATLAB code in my LaTeX document?

The matlab-prettifier package can be used to typeset MATLAB code and was written in response to a question on tex.stackexchange.

The lstlisting environment

After including the matlab-prettifier package in your document via

\usepackage{matlab-prettifier}

you can use the lstlisting environment to typeset MATLAB code:

\begin{lstlisting}[<options>]
MATLAB code...
\end{lstlisting}

where <options> is a comma-separated list of parameters whose values are set using key–value pairs (i.e., parameter=value).

• Note: The matlab-prettifier package is built around the listings package, enabling use of features provided by listings, including parameters within <options> of the lstlisting environment. However, some listings parameters should not be used, and readers are advised to consult the matlab-prettifier documentation for further details.

The visual appearance of typeset MATLAB code can be changed using the style parameter, which supports three values:

• Matlab-editor
• Matlab-bw
• Matlab-Pyglike

The following examples demonstrate how to use those styles.

Examples

Here is an example, using MATLAB code from matlab-prettifier’s documentation, which applies the Matlab-editor style:

\documentclass[a4paper]{article}
\usepackage{matlab-prettifier}
\begin{document}

\begin{lstlisting}[style=Matlab-editor]
%% Sample Matlab code
!mv test.txt test2.txt
A = [1, 2, 3;... foo
     4, 5, 6];
s = 'abcd';
for k = 1:4
  Disp(s(k)) % bar
end
%{
create row vector x, then reverse it
%}
x = linspace(0,1,101);
y = x(end:-1:1);
\end{lstlisting}
\end{document}

This example produces the following output:

The next example set values for the frame and numbers parameters provided by the listings package:

\documentclass[a4paper]{article}
\usepackage{matlab-prettifier}
\begin{document}

\begin{lstlisting}[
frame=single,
numbers=left,
style=Matlab-Pyglike]
%% Sample Matlab code
!mv test.txt test2.txt
A = [1, 2, 3;... foo
     4, 5, 6];
s = 'abcd';
for k = 1:4
  Disp(s(k)) % bar
end
%{
create row vector x, then reverse it
%}
x = linspace(0,1,101);
y = x(end:-1:1);
\end{lstlisting}
\end{document}

Using MATLAB code stored in a file

Instead of including MATLAB code directly within your LaTeX document, use the \lstinputlisting command to import and typeset code contained in an external file:

\lstinputlisting[<options>]{<filename>}

where

• <options> is a comma-separated list of parameters provided as key–value pairs (see above);
• <filename> is the path to a file containing MATLAB code.

For example, to import the file sample.m and typeset it in the Matlab-bw style you would write

\lstinputlisting[style=Matlab-bw]{sample.m}

The next example places a frame around the code, numbers the lines of code (on the left), and uses the Matlab-bw style:

\lstinputlisting[
frame=single,
numbers=left,
style=Matlab-editor
]{sample.m}

Select the Open this example in Overleaf link (see below) to automatically create an Overleaf project which includes the sample.m MATLAB code file.

main.tex

\documentclass[a4paper]{article}
\usepackage{matlab-prettifier}
\begin{document}
\title{Importing and typesetting MATLAB code contained in a file}
\lstinputlisting[
frame=single,
numbers=left,
style=Matlab-bw
]{sample.m}

\end{document}

sample.m

%% Sample Matlab code
!mv test.txt test2.txt
A = [1, 2, 3;... foo
     4, 5, 6];
s = 'abcd';
for k = 1:4
  Disp(s(k)) % bar
end
%{
create row vector x, then reverse it
%}
x = linspace(0,1,101);
y = x(end:-1:1);

 Open this example in Overleaf (it creates the sample.m file).
