#include "petscvec.h" PetscErrorCode VecMPISetGhost(Vec vv,PetscInt nghost,const PetscInt ghosts)Collective on Vec
|vv||- the MPI vector|
|nghost||- number of local ghost points|
|ghosts||- global indices of ghost points, these do not need to be in increasing order (sorted)|
This also automatically sets the ISLocalToGlobalMapping() for this vector.
You must call this AFTER you have set the type of the vector (with VecSetType()) and the size (with VecSetSizes()).
