#include "petscksp.h" PetscErrorCode PCDeflationSetSpaceToCompute(PC pc,PCDeflationSpaceType type,PetscInt size)Logically Collective
pc | - the preconditioner context | |
type | - deflation space type to compute (or PETSC_IGNORE) | |
size | - size of the space to compute (or PETSC_DEFAULT) |
-pc_deflation_compute_space <haar> | - compute PCDeflationSpaceType deflation space | |
-pc_deflation_compute_space_size <1> | - size of the deflation space |
The deflation space is computed in PCSetUp().
