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

section | - the section | |

field | - the field of 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 (or NULL if there is no symmetry or the permutation is the identity). | |

rots | - The field rotations symmetries for the given orientations (or NULL if there is no symmetry or the rotations are all identity). |
