DMGetCoordinates

Gets a global vector with the coordinates associated with the DM.

#include "petscdm.h"     
PetscErrorCode DMGetCoordinates(DM dm, Vec *c)

Not Collective

dm -the DM

c -global coordinate vector

This is a borrowed reference, so the user should NOT destroy this vector

Each process has only the local coordinates (does NOT have the ghost coordinates).

For DMDA, in two and three dimensions coordinates are interlaced (x_0,y_0,x_1,y_1,...) and (x_0,y_0,z_0,x_1,y_1,z_1...)
