Input Parameters

nep  - the nonlinear eigensolver context
viewer  - the viewer to display the reason

Options Database Keys

-nep_converged_reason  - print reason for convergence, and number of iterations

Note

To change the format of the output call PetscViewerPushFormat(viewer,format) before this call. Use PETSC_VIEWER_DEFAULT for the default, use PETSC_VIEWER_FAILED to only display a reason if it fails. The latter can be set in the command line with -nep_converged_reason ::failed
