#include "petscvec.h" PetscErrorCode VecCreateGhostBlockWithArray(MPI_Comm comm,PetscInt bs,PetscInt n,PetscInt N,PetscInt nghost,const PetscInt ghosts[],const PetscScalar array[],Vec *vv)Collective on MPI_Comm Many br
comm | - the MPI communicator to use Many br | |
bs | - block size Many br | |
n | - local vector length Many br | |
N | - global vector length (or PETSC_DECIDE to have calculated if n is given) Many br | |
nghost | - number of local ghost blocks Many br | |
ghosts | - global indices of ghost blocks (or NULL if not needed), counts are by block not by index, these do not need to be in increasing order (sorted) Many br | |
array | - the space to store the vector values (as long as n + nghost*bs) Many br |
n is the local vector size (total local size not the number of blocks) while nghost Many bris the number of blocks in the ghost portion, i.e. the number of elements in the ghost Many brportion is bs*nghost Many br
Many br
