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

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSGetConvergedReason(EPS eps,EPSConvergedReason *reason)

Not Collective

Input Parameter#

  • eps - the linear eigensolver context

Output Parameter#

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

Options Database Key#

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

Note#

If this routine is called before or doing the EPSSolve() the value of EPS_CONVERGED_ITERATING is returned.
