我正在尝试将一些 Matlab 代码的起始数字从 1 更改为 236。我尝试使用，firstline=236但编译后没有任何输出。
您能帮我将代码编号从 236 开始吗？
以下是我目前所掌握的信息：
\documentclass{book}
\usepackage{listings}
\usepackage{xcolor}
\usepackage[numbered,framed]{matlab-prettifier}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.m}
% detect if next step is an obstacle
if bug.isoccupied(robot + [dx; dy])
bug.message('(%d,%d) obstacle!', n);
bug.H(bug.j,:) = robot; % define hit point
bug.step = 2;
% get a list of all the points around the obstacle
bug.edge = edgelist(bug.occgridnav == 0, robot);
%bug.k = 2; % skip the first edge point, we are already there
bug.k = size(bug.edge,2)
else
n = robot + [dx; dy];
end
end % step 1
\end{filecontents*}
\lstdefinestyle{mystyle}{
numbers=left,
numberstyle=\small,
numbersep=8pt,
%language=Matlab,
style=Matlab-editor,
basicstyle=\ttfamily\small,
numbersep=22pt,
frame=none
}
\begin{document}
\lstinputlisting[%firstline = 236,
backgroundcolor=\color{blue!10},
style=Matlab-editor,
basicstyle=\mlttfamily\scriptsize,
caption={[First Change to the Bug2 Algorithm]{First Change to the Bug2 Algorithm}},
label = mat:line246]{\jobname.m}
\end{document}
答案1
正确的选项是firstnumber=236！
请参阅以下代码：
\documentclass{book}
\usepackage{listings}
\usepackage{xcolor}
\usepackage[numbered,framed]{matlab-prettifier}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.m}
% detect if next step is an obstacle
if bug.isoccupied(robot + [dx; dy])
bug.message('(%d,%d) obstacle!', n);
bug.H(bug.j,:) = robot; % define hit point
bug.step = 2;
% get a list of all the points around the obstacle
bug.edge = edgelist(bug.occgridnav == 0, robot);
%bug.k = 2; % skip the first edge point, we are already there
bug.k = size(bug.edge,2)
else
n = robot + [dx; dy];
end
end % step 1
\end{filecontents*}
\lstdefinestyle{mystyle}{
numbers=left,
numberstyle=\small,
numbersep=8pt,
%language=Matlab,
style=Matlab-editor,
basicstyle=\ttfamily\small,
numbersep=22pt,
frame=none
}
\begin{document}
\lstinputlisting[%
%firstline = 236,
firstnumber=236, % <==================================================
backgroundcolor=\color{blue!10},
style=Matlab-editor,
basicstyle=\mlttfamily\scriptsize,
caption={[First Change to the Bug2 Algorithm]{First Change to the Bug2 Algorithm}},
label = mat:line246
]{\jobname.m}
\end{document}
结果：
