DMPlexGetConeRecursiveVertices

Expand each given point into its cone points and do that recursively until we end up just with vertices.

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexGetConeRecursiveVertices(DM dm, IS points, IS *expandedPoints)

Not Collective

Input Parameters

• dm - The DMPLEX

• points - The IS of points, which must lie in the chart set with DMPlexSetChart()

Output Parameter

• expandedPoints - An array of vertices recursively expanded from input points

Notes

Like DMPlexGetConeRecursive() but returns only the 0-depth IS (i.e. vertices only) and no sections.

There is no corresponding Restore function, just call ISDestroy() on the returned IS to deallocate.
