PEPSTOARSetDimensions#

Sets the dimensions used for each subsolve step in case of doing spectrum slicing for a computational interval. The meaning of the parameters is the same as in PEPSetDimensions().

Synopsis#

#include "slepcpep.h" 
PetscErrorCode PEPSTOARSetDimensions(PEP pep,PetscInt nev,PetscInt ncv,PetscInt mpd)

Logically Collective

Input Parameters#

  • pep - the eigenproblem solver context

  • nev - number of eigenvalues to compute

  • ncv - the maximum dimension of the subspace to be used by the subsolve

  • mpd - the maximum dimension allowed for the projected problem

Options Database Key#

  • -pep_stoar_nev - Sets the number of eigenvalues

  • -pep_stoar_ncv - Sets the dimension of the subspace

  • -pep_stoar_mpd - Sets the maximum projected dimension
