列表：如何注释 Matlab 列表（Matlab 代码）（花括号、箭头、文本）

Question

我有一个 matlab 代码，我想像图片一样解释其中的一部分。或者任何其他想法都可以做得更好。

\documentclass{article}

\usepackage{listings}
\usepackage{color} %red, green, blue, yellow, cyan, magenta, black, white
\definecolor{mygreen}{RGB}{28,172,0} % color values Red, Green, Blue
\definecolor{mylilas}{RGB}{170,55,241}


\begin{document}


\lstset{language=Matlab,%
    %basicstyle=\color{red},
    breaklines=true,%
    morekeywords={matlab2tikz},
    keywordstyle=\color{blue},%
    morekeywords=[2]{1}, keywordstyle=[2]{\color{black}},
    identifierstyle=\color{black},%
    stringstyle=\color{mylilas},
    commentstyle=\color{mygreen},%
    showstringspaces=false,%without this there will be a symbol in the places where there is a space
    numbers=left,%
    numberstyle={\tiny \color{black}},% size of the numbers
    numbersep=9pt, % this defines how far the numbers are from the text
    emph=[1]{for,end,break},emphstyle=[1]\color{red}, %some words to emphasise
    %emph=[2]{word1,word2}, emphstyle=[2]{style},    
}


\section*{Matlab Code}

‎\lstinputlisting{WEIGHT.m}‎


\end{document}

WEIGHT.mmatlab文件

clc
clear all
n=input('Please Enter Number Of Grid Point    n=');
      %-------------
      x=zeros(n,1);A=zeros(n,n);
      %-------------
      for i=1:n
        x(i)=0.5*(1-cos((i-1)*pi/(n-1))); 
      end
      for i=1:n
         for j=1:n
              Pi=1;Pj=1;
            for m=1:n 
               if m~=i  
                  Pi=(x(i)-x(m))*Pi;
               end
               if m~=j  
                  Pj=(x(j)-x(m))*Pj;
               end   
            end
            if i~=j 
               A(i,j)=Pi/((x(i)-x(j))*Pj);
            end   
         end  
         for m=1:n  
             if m~=i
                A(i,i)=A(i,i)-A(i,m);
             end
         end   
      end

可能的解决方案是tikz

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{decorations.pathmorphing, decorations.pathreplacing, positioning}
\usepackage[numbered,framed]{matlab-prettifier}

\begin{document}


\begin{tikzpicture}

                      inner sep=1cm,minimum size=2mm},
        place/.style={rectangle,draw=green!50,fill=green!20,thick,
                      inner sep=0cm,minimum size=6mm}           
    ]%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

                         escapechar         = ",
                         ]%#########################    
        {WEIGHT.m} 
     ‎};

     \node  (1) [left=of  A,yshift= 5.2cm] {};
