AOPetscToApplicationPermuteReal#
Permutes an array of blocks of reals in the PETSc ordering to the application-defined ordering.
Synopsis#
#include "petscao.h"
PetscErrorCode AOPetscToApplicationPermuteReal(AO ao, PetscInt block, PetscReal array[])
Collective
Input Parameters#
ao - The application ordering context
block - The block size
array - The integer array
Output Parameter#
array - The permuted array
Notes#
The length of the array should be blockN, where N is length provided to the AOCreate() method that created the AO.
The permutation takes array[i_pet] –> array[i_app], where i_app is the index of ‘i’ in the application ordering and i_pet is the index of ‘i’ in the petsc ordering.
