DMCreateLocalVector#
Creates a local vector from a DM object.
Synopsis#
#include "petscdm.h"
#include "petscdmlabel.h"
#include "petscds.h"
PetscErrorCode DMCreateLocalVector(DM dm, Vec *vec)
Not Collective
Input Parameter#
dm - the
DMobject
Output Parameter#
vec - the local vector
Note#
A local vector usually has ghost locations that contain values that are owned by different MPI ranks. A global vector has no ghost locations.
