PEPSetTrackAll
Specifies if the solver must compute the residual of all approximate eigenpairs or not.
Synopsis
#include "slepcpep.h"
PetscErrorCode PEPSetTrackAll(PEP pep,PetscBool trackall)
Logically Collective
Input Parameters
| pep | - the eigensolver context
|
| trackall | - whether compute all residuals or not
|
Notes
If the user sets trackall=PETSC_TRUE then the solver explicitly computes
the residual for each eigenpair approximation. Computing the residual is
usually an expensive operation and solvers commonly compute the associated
residual to the first unconverged eigenpair.
The option '-pep_monitor_all' automatically activates this option.
