#include "petscpc.h" PetscErrorCode PCBJacobiGetSubKSP(PC pc,PetscInt *n_local,PetscInt *first_local,KSP *ksp[])Note Collective
| n_local | - the number of blocks on this processor, or NULL | |
| first_local | - the global number of the first block on this processor, or NULL | |
| ksp | - the array of KSP contexts |
Currently for some matrix implementations only 1 block per processor is supported.
You must call KSPSetUp() or PCSetUp() before calling PCBJacobiGetSubKSP().
Fortran Usage: You must pass in a KSP array that is large enough to contain all the local KSPs. You can call PCBJacobiGetSubKSP(pc,nlocal,firstlocal,NULL_OBJECT,ierr) to determine how large the KSP array must be.
