PEPErrorView
Displays the errors associated with the computed solution (as well as the eigenvalues).
Synopsis
#include "slepcpep.h"
PetscErrorCode PEPErrorView(PEP pep,PEPErrorType etype,PetscViewer viewer)
Collective on PEP
Input Parameters
| pep | - the eigensolver context
|
| etype | - error type
|
| viewer | - optional visualization context
|
Options Database Key
| -pep_error_absolute | - print absolute errors of each eigenpair
|
| -pep_error_relative | - print relative errors of each eigenpair
|
| -pep_error_backward | - print backward errors of each eigenpair
|
Notes
By default, this function checks the error of all eigenpairs and prints
the eigenvalues if all of them are below the requested tolerance.
If the viewer has format=PETSC_VIEWER_ASCII_INFO_DETAIL then a table with
eigenvalues and corresponding errors is printed.
