matlab-pretifier 包中不显示编号

Question

有人知道这是为什么吗？我尝试将文档类别从“Article”更改为“Beamer”，还尝试删除一堆包，但没有任何内容使 Matlab 编辑器样式上的编号出现。我从文档中复制粘贴了示例，但除了编号之外的所有内容都出现了。有人知道这是为什么吗？谢谢

示例（修订、精简的尝试）：

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{textcomp}
\usepackage{listings}
\usepackage{xcolor}
\usepackage{matlab-prettifier}


\begin{document}
\maketitle
\section*{Problem 1}
We verify the $LU$ decomposition of $T$ by following the $LU$ decomposition algorithm used from Homework 2, onward. This process is iterative, so it is helpful to identify the elements of $L$ by the stage of their iteration.

The algorithm goes like this:\\
\begin{lstlisting}[
style=Matlab-editor,
basicstyle=\mlttfamily,
escapechar=`,
]
function [L,U] = GE(A)
%The square matrix A has LU decomposition
[n,n] = size(A);
for k = 1:n-1

    A(k+1:n,k) = A(k+1:n,k)/A(k,k)
    %each element underneath the k'th diagonal element is
    %divided by said element.
    A(k+1:n,k+1:n) = A(k+1:n,k+1:n) - A(k+1:n,k)*A(k,k+1:n)
    %The elements of the lower-right submatrix of dimension
    %(n-k-1)x(n-k-1) are updated. See figures in the
    %explanation below.
end
L = eye(n,n) + tril(A,-1);
U = triu(A);
\end{lstlisting}

\end{document}

Answer 1

看来你需要

\usepackage[numbered]{matlab-prettifier}

启用编号，默认情况下不启用。（您也可以添加numbers=left到选项中lstlisting）。您还需要

\usepackage[T1]{fontenc}

获取正确的字体，如手册中所述matlab-prettifier：

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc} % you need this to get the fonts right
\usepackage[english]{babel}
\usepackage[numbered]{matlab-prettifier} % <-- add [numbered]

[n,n] = size(A);

    A(k+1:n,k) = A(k+1:n,k)/A(k,k)

L = eye(n,n) + tril(A,-1);
U = triu(A);
