#include "slepceps.h" PetscErrorCode EPSKrylovSchurSetDetectZeros(EPS eps,PetscBool detect)Logically Collective on eps
|eps||- the eigenproblem solver context|
|detect||- check for zeros|
|-eps_krylovschur_detect_zeros||- Check for zeros; this takes an optional bool value (0/1/no/yes/true/false)|
This flag is turned off by default, and may be necessary in some cases, especially when several partitions are being used. This feature currently requires an external package for factorizations with support for zero detection, e.g. MUMPS.
