Extra alignment tab has been changed to cr

提示如下错误:

Extra alignment tab has been changed to \cr. [\end{array}} \right]\end{split}]

查看报错行源码发现, 矩阵实际为4列, 然而只指定了3列的参数( ccc ):

\begin{equation*}
\begin{split}{\bm A} = \left[ {\begin{array}{ccc}
{{a_{11}}}&{{a_{12}}}& \cdots &{{a_{1n}}}\\
{{a_{21}}}&{{a_{22}}}& \cdots &{{a_{2n}}}\\
 \vdots & \vdots & \ddots & \vdots \\
{{a_{n1}}}&{{a_{n2}}}& \cdots &{{a_{nn}}}
\end{array}} \right]\end{split}
\end{equation*}

将 ccc 改为 cccc 即可.
