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 PEPConvergedReason for 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.
