TikzEdt 中向量中的子节点

Question

我尝试在两个不同的节点中显示两个向量，然后使用箭头链接一些元素。

\tikzstyle{line} = [draw, -latex']        
    \begin{tikzpicture}[node distance = 2cm,auto,remember picture]
        % Place nodes       
        \node [draw,rounded corners] (node1) {$\matrix[mymatrix, name=M1]{
                                                                1 \\
                                                        |[!]|   2\rho\pi \\
                                                        |[draw,rounded corners,fill=blue]|   3\\
                                                    }$};

     \node [draw,rounded corners] (node1) {$\matrix[mymatrix, name=M2]{
                                                                4 \\
                                                        |[!]|   2\lambda\pi \\
                                                        |[draw,rounded corners,fill=yellow]|   3\\
                                                    }$};    
   \draw [red, >=stealth, <->, shorten <= 3pt, shorten >=3 pt]
 (M1-2-1.south east) to[bend left=60] (M2-3-1.north east);     
    \end{tikzpicture}

在我的 Tikz 序言中，我有以下包声明

\documentclass{article,fleqn}
\usepackage{tikz,amsmath, amssymb,bm,color,automata,matrix,positioning,fit}
\usepackage[margin=0cm,nohead]{geometry}
\usepackage[active,tightpage]{preview}
\usetikzlibrary{shapes,arrows}
% needed for BB
\usetikzlibrary{calc}
\usetikzlibrary{topaths}
\usetikzlibrary{decorations}
\usetikzlibrary{decorations.pathmorphing}
\usetikzlibrary{calc}
\usetikzlibrary{tikzmark}

\usetikzlibrary{topaths}
\usetikzlibrary{backgrounds}
\usepackage{todonotes}

%To be able to use 
\tikzset{
    !/.style = {
        fill=yellow!30,
    },
    mymatrix/.style = {
        matrix of math nodes,
        left delimiter  = (,
        right delimiter = ),
        nodes={minimum width=6ex},
    }
}
\tikzset{every picture/.style=remember picture}

\PreviewEnvironment{tikzpicture}

可能，我使用的量超出了要求，但我确实还有其他文件。Tikz 给出了以下错误：

Package amsmath Error: Old form '\matrix' should be \begin{\matrix}..de[draw,rounded corners](node1){$\matrix(followed by: [mymatrix, na 

我已经在 Latex 中使用过它（感谢一些 stackeschange 用户的帮助），但我似乎无法让它在 Tikz 中工作如果有人有建议，请...

干杯。

您的代码有很多语法问题。

在下面的代码中，我展示了两种可能性；突出显示是使用\tcbhighmath来自的命令完成的tcolorbox包；附加箭头是在tikzmark图书馆：

\documentclass{article}
\usepackage{amsmath}
\usepackage[most]{tcolorbox}
\usetikzlibrary{tikzmark,positioning}

\tcbset{
myformulai/.style={
  colback=yellow!30,
  colframe=yellow!30,
  left=2pt,right=2pt,top=0pt,bottom=0pt,
  },
myformulaii/.style={
  colback=blue!30,
  boxrule=0.4pt,
  colframe=blue!30!black,
  left=2pt,right=2pt,top=0pt,bottom=0pt,
  },
myformulaiii/.style={
  colback=white,
  colframe=black,
  boxrule=0.4pt,
  left=2pt,right=2pt,top=0pt,bottom=0pt,
  }
}

\begin{document}

\[
\tcbhighmath[myformulaiii]{%
\begin{pmatrix}
     1 \\ \tcbhighmath[myformulai]{2\rho\pi\tikzmark{a}} \\ \tcbhighmath[myformulaii]{3}
\end{pmatrix}}
\]

\[
\tcbhighmath[myformulaiii]{%
\begin{pmatrix}
     1 \\ \tcbhighmath[myformulai]{2\rho \pi} \\ \tcbhighmath[myformulaii]{3}\tikzmark{b}
\end{pmatrix}}
\]

\begin{tikzpicture}[remember picture, overlay]
\draw [red, >=stealth, <->, shorten <= 3pt, shorten >=3 pt,overlay]
 (pic cs:a) to[bend left=90] (pic cs:b);
\end{tikzpicture}

\begin{center}
\begin{tikzpicture}[remember picture, overlay]
\node[rounded corners,draw] (mat1)
{
$\begin{pmatrix}
     1 \\ \tcbhighmath[myformulai]{2\rho\pi\tikzmark{c}} \\ \tcbhighmath[myformulaii]{3}
\end{pmatrix}$
};

\node[rounded corners,draw,below=of mat1] (mat2)
{
$\begin{pmatrix}
     1 \\ \tcbhighmath[myformulai]{2\rho \pi} \\ \tcbhighmath[myformulaii]{3}\tikzmark{d}
\end{pmatrix}$
};

\draw [red, >=stealth, <->, shorten <= 3pt, shorten >=3 pt,overlay]
 (pic cs:c) to[bend left=90] (pic cs:d);
\end{tikzpicture}
\end{center}

\end{document}
