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. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?53140> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
