PEPGetConvergedReason#
Gets the reason why the PEPSolve() iteration was stopped.
Synopsis#
#include "slepcpep.h"
PetscErrorCode PEPGetConvergedReason(PEP pep,PEPConvergedReason *reason)
Not Collective
Input Parameter#
pep - the polynomial eigensolver context
Output Parameter#
reason - negative value indicates diverged, positive value converged, see
PEPConvergedReasonfor the possible values
Options Database Key#
-pep_converged_reason - print reason for convergence/divergence, and number of iterations
Note#
If this routine is called before or doing the PEPSolve() the value of
PEP_CONVERGED_ITERATING is returned.
