### Synopsis

    #include "petscdmlabel.h"
    PetscErrorCode DMGetDimPoints(DM dm, PetscInt dim, PetscInt *pStart, PetscInt *pEnd)

Collective on DM

### Input Parameters

| dm | - the DM
| dim | - the dimension

### Output Parameters

| pStart | - The first point of the given dimension
| pEnd | - The first point following points of the given dimension

### Note

The points are vertices in the Hasse diagram encoding the topology. This is explained in http://arxiv.org/abs/0908.4427. If not points exist of this dimension in the storage scheme, then the interval is empty.

### Keywords
