Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexGetMeet(DM dm, PetscInt numPoints, const PetscInt points[], PetscInt *numCoveringPoints, const PetscInt **coveringPoints)

Not Collective

Input Parameters

• dm - The DMPLEX object

• numPoints - The number of input points for the meet

• points - The input points, of length numPoints

Output Parameters

• numCoveringPoints - The number of points in the meet

• coveringPoints - The points in the meet, of length numCoveringPoints

Fortran Notes

coveringPoints must be declared with

  PetscInt, pointer :: coveringPoints(:)

The numCoveredPoints argument is not present in the Fortran binding since it is internal to the array.
