Hello All, I use MatAXPY (DIFFERENT_NONZERO_PATTERN), with petsc-3.4.3. Works ok, no problem, however in -log_summary as result MatAXPY I have more destructions than creations, each time MatAXPY was used. I have tested this for MATMPIAIJ.
Valgring don't show anything wrong with that. Kind regards, Lukasz
