# 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.
