EPSKrylovSchurSetLocking#
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 linear eigensolver 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 behavior can be changed so that all directions are kept in the working subspace even if already converged to working accuracy (the non-locking variant).
