ISPermutation#
PETSC_TRUE or PETSC_FALSE depending on whether the index set has been declared to be a permutation.
Synopsis#
#include "petscis.h"
PetscErrorCode ISPermutation(IS is, PetscBool *perm)
Logically Collective
Input Parameter#
is - the index set
Output Parameter#
perm - PETSC_TRUE if a permutation, else PETSC_FALSE
Note: If it is not already known that the IS is a permutation (if ISSetPermutation() or ISSetInfo() has not been called), this routine will not attempt to compute whether the index set is a permutation and will assume perm is PETSC_FALSE. To compute the value when it is not already known, use ISGetInfo() with the compute flag set to PETSC_TRUE.
