用Matlab计算大矩阵的Jordan范式

Question

嗨

我想在Matlab中计算大循环矩阵的Jordan范式（即365×365阶）

例如，4x4圆形矩阵的形式如下：

A = [0 1 0 0 ; 0 0 1 0 ; 0 0 0 1 ;1 0 0 0]

当我要求AA尺寸为365 x 365时：

[v,j] = eng.jordan(mtdb_G_time_cyc,nargout = 2)

我得到这个错误：

Error using symengine (line 58)
Similarity matrix is too large.

Error in sym/mupadmexnout (line 875)
    out = mupadmex(fcn,args{:});

Error in sym/jordan (line 34)
    [Vsym,Jsym] = mupadmexnout('symobj::jordan',A,'All');

Error in double/jordan (line 25)
[V,J] = jordan(sym(A));

Traceback (most recent call last):

实际上，我通过python调用Matlab函数。在

有什么方法可以计算乔丹形式吗？在

我很感激你的解决办法
