Choose between locking and non-locking variants of the Krylov-Schur method.
Synopsis
#include "slepceps.h"
PetscErrorCode EPSKrylovSchurSetLocking(EPS eps,PetscBool lock)
Logically Collective
Input Parameters
| eps | - the eigenproblem solver context
|
| lock | - true if the locking variant must be selected
|
Options Database Key
| -eps_krylovschur_locking | - Sets the locking flag

Notes
The default is to lock converged eigenpairs when the method restarts.
This behaviour can be changed so that all directions are kept in the
working subspace even if already converged to working accuracy (the
non-locking variant).
