Cholecky decomposition with PARDISO

[leonid_i]

Hi, everyone,

I have recently run accross a problem, which requires manipulations with large sparse matrices, in particular, it is desired to efficiently compute Cholesky decomposition of a symmetric matrix of the order >=30000. I checked that PARDISO can factorize such matrix relatively fast (at phase 22), but how do I exctract the factored matrix without actually solving the associated system of equations?

Thanks,

Leonid.

Leonid, there is no such opportunity for the current version of PARDSIO.

Hello together!

I am also interested in extracting the Cholesky Factorization from PARDISO. Are there any news? Is it now possible to extract it??

Greetings, Oliver

No, PARDISO does not provide such an opportunity
