PetscSectionRestorePointSyms#

Restore the symmetries returned by PetscSectionGetPointSyms()

Synopsis#

#include "petscsection.h"   
PetscErrorCode PetscSectionRestorePointSyms(PetscSection section, PetscInt numPoints, const PetscInt *points, const PetscInt ***perms, const PetscScalar ***rots)

Not Collective

Input Parameters#

  • section - the section

  • 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()).

  • 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
