# DMGetCoordinates

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

### Synopsis

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

Not Collective

### Input Parameter

dm -the DM

### Output Parameter

c -global coordinate vector

### Note

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...)
