Hi,
Recently I solved a sparse non-symmetric real matrix equation with 2,785,003 unknowns,
The question is that I found Negative output of IPARM (18), which is the number of nonzeros in factors... , what's the meaning of this case?
As a result, the solution produced is wrong.
I wonder what's the problem, could anyone give me some information? Thanks a lot!
