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