Displays the reason an SVD solve converged or diverged.

Synopsis#

#include "slepcsvd.h" 
PetscErrorCode SVDConvergedReasonView(SVD svd,PetscViewer viewer)

Collective

Input Parameters#

  • svd - the singular value solver context

  • viewer - the viewer to display the reason

Options Database Keys#

  • -svd_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 -svd_converged_reason ::failed
