PEPConvergedReasonView#
Displays the reason a PEP solve converged or diverged.
Synopsis#
#include "slepcpep.h"
PetscErrorCode PEPConvergedReasonView(PEP pep,PetscViewer viewer)
Collective
Input Parameters#
pep - the polynomial eigensolver context
viewer - the viewer to display the reason
Options Database Key#
-pep_converged_reason - print reason for convergence/divergence, and number of iterations
Notes#
Use PEPConvergedReasonViewFromOptions() to display the reason based on values
in the options database.
To change the format of the output call PetscViewerPushFormat() before this
call. Use PETSC_VIEWER_DEFAULT for the default, or PETSC_VIEWER_FAILED to only
display a reason if it fails. The latter can be set in the command line with
-pep_converged_reason ::failed.
