#include "slepcpep.h" PetscErrorCode PEPGetConvergedReason(PEP pep,PEPConvergedReason *reason)Not Collective
| pep | - the polynomial eigensolver context |
| reason | - negative value indicates diverged, positive value converged |
| -pep_converged_reason | - print the reason to a viewer |
| PEP_CONVERGED_TOL | - converged up to tolerance | |
| PEP_CONVERGED_USER | - converged due to a user-defined condition | |
| PEP_DIVERGED_ITS | - required more than max_it iterations to reach convergence | |
| PEP_DIVERGED_BREAKDOWN | - generic breakdown in method | |
| PEP_DIVERGED_SYMMETRY_LOST | - pseudo-Lanczos was not able to keep symmetry |
Can only be called after the call to PEPSolve() is complete.
