NEPGetConvergedReason#

Gets the reason why the NEPSolve() iteration was stopped.

Synopsis#

#include "slepcnep.h" 
PetscErrorCode NEPGetConvergedReason(NEP nep,NEPConvergedReason *reason)

Not Collective

Input Parameter#

  • nep - the nonlinear eigensolver context

Output Parameter#

  • reason - negative value indicates diverged, positive value converged, see NEPConvergedReason for the possible values

Options Database Key#

  • -nep_converged_reason - print reason for convergence/divergence, and number of iterations

Note#

If this routine is called before or doing the NEPSolve() the value of NEP_CONVERGED_ITERATING is returned.
