ISEqualUnsorted#
Compares if two index sets have the same indices.
Synopsis#
#include "petscis.h"  
PetscErrorCode ISEqualUnsorted(IS is1, IS is2, PetscBool *flg)
Collective
Input Parameters#
- is1 - first index set to compare 
- is2 - second index set to compare 
Output Parameter#
- flg - output flag, either - PETSC_TRUE(if both index sets have the same indices), or- PETSC_FALSEif the index sets differ by size or by the set of indices)
Note#
Unlike ISEqual(), this routine does NOT sort the contents of the index sets before
the comparison is made, i.e., the order of indices is important.
Each MPI rank must have the same indices.
