EPSErrorView
Displays the errors associated with the computed solution (as well as the eigenvalues).
Synopsis
#include "slepceps.h"
PetscErrorCode EPSErrorView(EPS eps,EPSErrorType etype,PetscViewer viewer)
Collective on eps
Input Parameters
| eps | - the eigensolver context
|
| etype | - error type
|
| viewer | - optional visualization context
|
Options Database Keys
| -eps_error_absolute | - print absolute errors of each eigenpair
|
| -eps_error_relative | - print relative errors of each eigenpair
|
| -eps_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.
