Get the half-open interval for all points of a given dimension

PetscErrorCode DMGetDimPoints(DM dm, PetscInt dim, PetscInt *pStart, PetscInt *pEnd)

Collective

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 https://arxiv.org/abs/0908.4427. If no points exist of this dimension in the storage scheme, then the interval is empty.
