Use <A HREF="../Vec/VecDuplicate.html#VecDuplicate">VecDuplicate</A>() or <A HREF="../Vec/VecDuplicateVecs.html#VecDuplicateVecs">VecDuplicateVecs</A>() to form additional vectors of the
same type as an existing vector.
<P>
If the user-provided array is NULL, then <A HREF="../Vec/VecViennaCLPlaceArray.html#VecViennaCLPlaceArray">VecViennaCLPlaceArray</A>() can be used
at a later stage to SET the array for storing the vector values.
<P>
PETSc does NOT free the array when the vector is destroyed via <A HREF="../Vec/VecDestroy.html#VecDestroy">VecDestroy</A>().
The user should not free the array until the vector is destroyed.
