Use <A HREF="../Vec/VecDestroyVecs.html#VecDestroyVecs">VecDestroyVecs</A>() to free the space. Use <A HREF="../Vec/VecDuplicate.html#VecDuplicate">VecDuplicate</A>() to form a single
vector.
<P>
<H3><FONT COLOR="#CC3333">Fortran Note</FONT></H3>
The Fortran interface is slightly different from that given below, it
requires one to pass in V a <A HREF="../Vec/Vec.html#Vec">Vec</A> (integer) array of size at least m.
See the Fortran chapter of the users manual and petsc/src/vec/vec/examples for details.
