# Choosing lines from a Matlab file using matlab-prettifier

I have been using the matlab-prettifier package a couple of times. So far I have only imported the entire .m-file to be shown in my documents using:

\usepackage[numbered,framed]{matlab-prettifier}

\let\ph\mlplaceholder % shorter macro
\lstMakeShortInline"

\lstset{
style              = Matlab-editor,
basicstyle         = \mlttfamily,
escapechar         = ",
mlshowsectionrules = true,
}


in the preamble and:

\lstinputlisting{../mFile.m}


in the documents.

In my upcoming beamer presentation I want to show only some part of my code, e.g. lines 10-15. Is this somehow (easily) possible?

I usually use the documentclass memoir for my writings. Is the solution the same/easier here? (If it exists.)

matlab-prettifier is built on top of listings. Hence you can use linerange={<first1>-<last1>,<first2>-<last2>, and so on} (which is a listings option) to print selected lines. For example:

\lstinputlisting[caption = {Sample code from Matlab with line range},linerange={3-6}]{sample.m}


Now lines 3-6 of sample.m will be printed.

Code (from one of Jubobs old answer):

\documentclass{memoir}

\usepackage[T1]{fontenc}
\usepackage{bigfoot} % to allow verbatim in footnote
\usepackage[numbered,framed]{matlab-prettifier}

\usepackage{filecontents}
\begin{filecontents*}{person.m}
classdef person
properties %(here, properties is a keyword)
mass=80;
height=1.80;
end
methods
function BMI = getBMI(height,weight)
BMI = person.mass/person.mass²;
end
end
end
\end{filecontents*}

\begin{filecontents*}{sample.m}
%% Code sections are highlighted.
% System command are supported...
!gzip sample.m
%   ... as is line continuation.
A = [1, 2, 3,  ... % (mimicking the ouput is good)
4, 5, 6]
fid = fopen('testFile.text', 'w')
for i=1:10
fprintf(fid,'%6.2f \n', i);
end
x=1; %% this is just a comment, though
% Context-sensitive keywords get highlighted correctly...
p = properties(mydate); %(here, properties is a function)
x = linspace(0,1,101);
y = x(end:-1:1)
%   ... even in nonsensical code.
]end()()(((end end)end ))))end (function end
%{
block comments are supported
%} even
are
\end{filecontents*}

\let\ph\mlplaceholder % shorter macro
\lstMakeShortInline"

\lstset{
style              = Matlab-editor,
basicstyle         = \mlttfamily,
escapechar         = ",
mlshowsectionrules = true,
}

\begin{document}

\lstlistoflistings

\lstinputlisting[caption = {Some class definition}]{person.m}

Before you use any "for"~loop, refresh your memory on Matlab blocks.%
\footnote{Any occurence of "for" must have a matching "end".}

\lstinputlisting[caption = {Sample code from Matlab with line range},linerange={3-6}]{sample.m}
%% \lstinputlisting[caption = {Sample code from Matlab with line range},linerange={3-6,10-15}]{sample.m}
\lstinputlisting[caption = {Sample code from Matlab}]{sample.m}
\pagebreak

\begin{lstlisting}[caption = {For educational purposes}]
% example of while loop using placeholders
while "\ph{condition}"
break
else
% do something useful
end
% do more things
end
\end{lstlisting}

\end{document}


• This is same for memoir too.

• The ... somehow got replaced by \dots. Is that something your editor does automatically? Nov 15 '14 at 13:45
• @Jubobs Yes, winedt does such things whether we like or not. But only if we install some macros, hence no default behaviour.

You can do this within the listings package, using the following syntax.

\lstinputlisting[firstline=10, lastline=15]{../mFile.m}


This will work in beamer and memoir, as well as other classes.
