# 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.
