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 on eps

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.
