在matlab中索引矩阵

Question

所以我有一个运行j次的脚本。以下行产生错误：

[evec(:,:,j), eval(:,:,j)] = eig(T(:,:,j));

Error using mupadmex
Error in MuPAD command: Cannot compute the explicit
representation of the eigenvalues; use
'numeric::eigenvectors'. [linalg::eigenvectors]

Error in sym/mupadmexnout (line 2080)
        out = mupadmex(fcn,args{:});

Error in sym/eig (line 68)
        [V,D,p] = mupadmexnout('symobj::eigenvectors',A);

Error in SingleLayer (line 86)
[evec(:,:,j), eval(:,:,j)] = eig(T(:,:,j));

这是我收到的错误消息。我是否正确创建3“表”（不知道如何描述）这样。我
