Question

您好

我想在Matlab中计算Jordan正规形式的大圆矩阵（即365 x 365的顺序）

例如，4x4圆形矩阵具有以下形式：

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

当我将其称为AA时，其尺寸为365 x 365：

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

我收到此错误：

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调用了Matlab函数。

有什么方法可以计算乔丹形式吗？

我很感激您的解决方案
