VecDuplicateVecs
Creates several vectors of the same type as an existing vector.
Synopsis
#include "petscvec.h"
PetscErrorCode VecDuplicateVecs(Vec v,PetscInt m,Vec *V[])
Collective on Vec Many br
Input Parameters
| m | - the number of vectors to obtain Many br |
| v | - a vector to mimic Many br |
Output Parameter
V -location to put pointer to array of vectors Many br
Notes
Use VecDestroyVecs() to free the space. Use VecDuplicate() to form a single Many brvector. Many br
Fortran Note
The Fortran interface is slightly different from that given below, it Many brrequires one to pass in V a Vec (integer) array of size at least m. Many brSee the Fortran chapter of the users manual and petsc/src/vec/vec/examples for details. Many br
