Hi all,

I have seen that Stan has function eigenvalues_sym(matrix A) to compute the eigenvalues of a symmetric matrix. There is a topic here in 2018.

I am asking whether Stan has a function to compute eigenvalues for non symmetric matrices now (2023)?

Or do you have any ideas for calculating them in other ways? I am sure that all eigenvalues are positive as I can get them using R (eigen).

Best regards,

Zhenkun
