[petsc-users] Store the ILU preconditioner matrices

[Luca Mechelli]

Dear all,

Does someone know how to get the ILU matrices ( L, U and the permutation matrix P) computed by the ILU preconditioner?

Like the Matlab command: [L,U,P]= ilu(A,setup)
Is this possible in PETSc?

Thank you a lot,
Best regards,
Luca Mechelli
