Accessing the diagonal of the factorized matrix using DSS

postaquestion's picture

Is it possible to access the diagonal of the factorized matrix using the Direct Sparse Solver?According to the MKL manual the factorized matrix is controlled by an opaque handle but its structure is not documented. Thanks in advance.

Please see some comments for our expert for this question:


It can not access this diagonal of the factorized matrix now. The factorized matrix is stored in internal special form and this form depends on algorithms and optimization. We saw such request before but we are still looking atitat this time.


Thanks,


Chao
