来自多个来源的复杂 TikZ 图，其子图标记边

Question

我会将两个\matrixes 放在同一个tikzpicture名为m和中m2，然后您可以轻松地用绘制连接箭头\draw [->] (m) -- (m2);。

您可以在路径上放置多个节点。例如，

\draw (a) -- (b)
   node[above,midway] {foo}
   node[below,midway] {bar};

下面的代码就是所使用的基本原理。

我还建议使用循环来绘制每个矩阵中的连接。您可以根据需要使用或忽略此方法。

您还指定了matrix of nodes（我将其更改为matrix of math nodes），但您没有使用它。使用该选项，并nodes={point}设置节点的一般样式，您可以A在单元格中写入，而不是\node [point] {A};。此类节点会自动命名为<matrix name>-<row number>-<column number>，例如m-3-2。
