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
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
Note#
Use VecDestroyVecs() to free the space. Use VecDuplicate() to form a single
vector.
Fortran Notes#
The Fortran interface is slightly different from that given below, it
requires one to pass in V a Vec array of size at least m.
See the PETSc for Fortran Users for details.
