Restore the symmetries returned by PetscSectionGetFieldPointSyms()


#include "petscvec.h"   
PetscErrorCode PetscSectionRestoreFieldPointSyms(PetscSection section, PetscInt field, PetscInt numPoints, const PetscInt *points, const PetscInt ***perms, const PetscScalar ***rots)
Not collective

Input Parameters

section - the section
field - the field number
numPoints - the number of points
points - an array of size 2 * numPoints, containing a list of (point, orientation) pairs. (An orientation is an arbitrary integer: its interpretation is up to sym. Orientations are used by DM: for their interpretation in that context, see DMPlexGetConeOrientation()).

Output Parameter

perms - The permutations for the given orientations: set to NULL at conclusion
rots - The field rotations symmetries for the given orientations: set to NULL at conclusion
