Can I free original matrix after Pardiso factorization

Hi,

I am wondering when can I release the original matrix memory (*a, *ia, *ja)? Since pardiso will keep the factor matrix internally, I think the original matrix memory can be release after factorization.

Any comments would be great.

Thanks

Lengfei

Hi Gennady,

Thanks for the reply. I tried several matrices. Some of them work fine when I free the original matrix before going to solve phase. However, one case gave me zero Pivot error. If I free the original matrix after all solve steps, it will run without giving any error.

Thanks
