PetscMergeIntArrayPair
Merges two SORTED integer arrays that share NO common values along with an additional array of integers. The additional arrays are the same length as sorted arrays and are merged in the order determined by the merging of the sorted pair.
Synopsis
#include "petscsys.h"
PetscErrorCode PetscMergeIntArrayPair(PetscInt an,const PetscInt aI[], const PetscInt aJ[], PetscInt bn, const PetscInt bI[], const PetscInt bJ[], PetscInt *n, PetscInt **L, PetscInt **J)
Not Collective
Input Parameters
| an | - number of values in the first array
|
| aI | - first sorted array of integers
|
| aJ | - first additional array of integers
|
| bn | - number of values in the second array
|
| bI | - second array of integers
|
| bJ | - second additional of integers
|
Output Parameters
| n | - number of values in the merged array (== an + bn)
|
| L | - merged sorted array
|
| J | - merged additional array
|
Notes
if L or J point to non-null arrays then this routine will assume they are of the approproate size and use them, otherwise this routine will allocate space for them
