Four execution steps

[programmer85]

Acording to manual, steps to be made using PARDISO are :

PARDISO performs four tasks:
(1) analysis and symbolic factorization (phase = 11)
(2) numerical factorization (phase = 22)
(3) forward and backward substitution including iterative refinement (phase = 33)
(4) termination to release all internal solver memory (phase = -2)

If I have one-based indexing matrix (nonzeros, columns indecies, and first of row element indices) - can I :

[1] avoid step (3)

[2] avoid step (2) and (3)

Hello,

No, you can not avoid this steps in both of this cases. That steps are an important stages of the solution process. One-based indexing is just a legacy of FORTRAN using.
