PETSc version 3.17.5
PetscSortIntWithIntCountArrayPair
Sorts an array of integers in place in increasing order; changes an integer array and a PetscCount array to match the sorted first array.
Synopsis
#include "petscsys.h"
PetscErrorCode PetscSortIntWithIntCountArrayPair(PetscCount n,PetscInt X[],PetscInt Y[],PetscCount Z[])
Not Collective
Input Parameters
| n | - number of values
|
| X | - array of integers
|
| Y | - second array of integers (first array of the pair)
|
| Z | - third array of PetscCounts (second array of the pair)

Notes
Usually X, Y are matrix row/column indices, and Z is a permutation array and therefore Z's type is PetscCount to allow 2B+ nonzeros even with 32-bit PetscInt.
