QEPSetTrackAll
Specifies if the solver must compute the residual of all approximate eigenpairs or not.
Synopsis
#include "slepcqep.h"
PetscErrorCode QEPSetTrackAll(QEP qep,PetscBool trackall)
Logically Collective on QEP
Input Parameters
| qep | - 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 options '-qep_monitor_all' and '-qep_monitor_draw_all' automatically
activates this option.
