当有子标题时，如何在列表中显示中心标题（列表标题和子标题类之间存在工作冲突）？

Question

实际上，当您使用和时caption，和之间存在一些不兼容性......listingsxleftmarginxrightmargin

在不更改任何来自某个包的命令的情况下，想到的一件事就是将列表插入居中的小页面内。

因此，删除以下行

  xleftmargin=3.5cm,
  xrightmargin=3.5cm

从内部\lstset

并以以下方式将您的列表插入到您的文档中：

\begin{center}
\begin{minipage}{.5\textwidth}
\begin{lstlisting}[title={Script 1: A program in Matlab to estimate the total area under $\sin(x)$}]
a=0;
b=pi/2;
h=max(feval(@func,linspace(a,b,n)));
x=a+(b-a)*rand(n,1);
y=h*rand(n,1);
N=0;
f=sin(x);
for j=1:n
    if y(j)<=f(j)
        N=N+1;
    end
end
ans=N/n*h*(b-a)
\end{lstlisting}
\end{minipage}
\end{center}

因此，以下 MWE

只是一些评论：

由于我不知道从哪里获取该包ecrc，因此我从您的 MWE 中删除了一些代码。
该包caption不需要被加载，因为它已经被包加载了subcaption。

我不知道您是否出于特定原因使用title而不是caption。如果原因是要删除标题中的“Listing”一词，您可以执行以下操作：

a. 在序言中放入以下一行：

\renewcommand{\lstlistingname}{Script}

b. 替换

\begin{lstlisting}[title={Script 1: A program in Matlab to estimate the total area under $\sin(x)$}]

和

\begin{lstlisting}[caption={A program in Matlab to estimate the total area under $\sin(x)$}]
