PetscErrorCode PEPSTOARSetLocking(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_stoar_locking  - Sets the locking flag


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).
