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.
