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
Input Parameters
|  | m | - the number of vectors to obtain | 
|  | v | - a vector to mimic | 
Output Parameter
V  -location to put pointer to array of vectors
Notes
Use VecDestroyVecs() to free the space. Use VecDuplicate() to form a single
vector.
Fortran Note
The Fortran interface is slightly different from that given below, it
requires one to pass in V a Vec (integer) array of size at least m.
See the Fortran chapter of the users manual and petsc/src/vec/vec/examples for details.
