This is an example of a matrix.
\begin{tikzpicture}
\matrix [matrix of math nodes,left delimiter=(,right delimiter=),ampersand replacement=\&] (m)
{
8 \& 8 \& 1 \& 6 \\
3 \& 8 \& 5 \& 7 \\
4 \& 8 \& 9 \& 5 \\
};
\draw[color=red] (m-1-1.north west) -- (m-1-3.north east) -- (m-2-3.south east) -- (m-2-1.south west) -- (m-1-1.north west);
\draw[color=red,double,implies-](m-1-2.north) -- +(0,0.3);
\end{tikzpicture}

我尝试在 Beamer 中绘制一个带有方框的矩阵，根据这，我通过插入以下内容修复了“Package pgfbasematrix Error: Single ampersand used with mistakes catcode”错误这.现在我收到错误
! Missing \endcsname inserted.
<to be read again>
\pgf@arrows@invertimplies
l.23 \end{frame}
我该如何修复它？
