SVDErrorView#
Displays the errors associated with the computed solution (as well as the singular values).
Synopsis#
#include "slepcsvd.h"
PetscErrorCode SVDErrorView(SVD svd,SVDErrorType etype,PetscViewer viewer)
Collective
Input Parameters#
svd - the singular value solver context
etype - error type
viewer - optional visualization context
Options Database Keys#
-svd_error_absolute - print absolute errors of each singular triplet
-svd_error_relative - print relative errors of each singular triplet
-svd_error_norm - print errors relative to the matrix norms of each singular triplet
Notes#
By default, this function checks the error of all singular triplets and prints the singular values if all of them are below the requested tolerance. If the viewer has format=PETSC_VIEWER_ASCII_INFO_DETAIL then a table with singular values and corresponding errors is printed.
