PEPQArnoldiSetLocking
Choose between locking and non-locking variants of the Q-Arnoldi method.
Synopsis
#include "slepcpep.h"
PetscErrorCode PEPQArnoldiSetLocking(PEP pep,PetscBool lock)
Logically Collective on PEP
Input Parameters
| pep | - the eigenproblem solver context
|
| lock | - true if the locking variant must be selected
|
Options Database Key
-pep_qarnoldi_locking - Sets the locking flag
Notes
The default is to keep all directions in the working subspace even if
already converged to working accuracy (the non-locking variant).
This behaviour can be changed so that converged eigenpairs are locked
when the method restarts.
Note that the default behaviour is the opposite to Krylov solvers in EPS.
