Incomplete LU factorisation

Open djelovina opened this issue 2 years ago • 2 comments

Is there a way to call incomplete ILU0 factorization? Assuming, there is no ILU0 is there any test for SpTRSV only, where I get ILU0 matrices externally from another code?

SuprLU_DIST does not have ILU. Sequential SuperLU has good support of ILU.

Unfortunately, you cannot directly use SpTRSV, unless you put your ILU0 matrix in the SuperLU's internal L & U formats.
