Problem with pardiso solver

BenJakobs — Fri, 11 Aug 2023 13:26:08 GMT

Hello,

I've been trying to solve a sparse matrix following the example given in "pardiso_sym.c". However, I've noticed that if you back substitute the solution obtained from that example, the RHS are not found again. i.e., if I'm trying to solve A*x = b, I know A and b, pardiso solves for x, I plug x back into the equation and should obtain b, however, that is not the case!

Can anyone help me with this? Or has encountered this problem before?

Kind regards,

Ben Jakobs

Never mind, there is no problem with the solver! Big blunder on my behalf.
