Follow-up Comment #30, bug #53140 (project octave):
Marco,
As for setting
Control (UMFPACK_IRSTEP) = 1;
The paper discusses a stopping criterion for iterative refinement
but I don't understand whether umfpack implements that or just unconditionally
performs the given number of iterative refinements?
In this letter case I would agree to setting the number to 1 and documenting
it, in the former it should not have any significant effect though ...
I don't know much about items 2)-4) but from your comments below
I would agree with your choices.
