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.
