See the file include/petscvec.h for a complete list of matrix
operations, which all have the form VECOP_<OPERATION>, where
<OPERATION> is the name (in all capital letters) of the
user interface routine (e.g., <A HREF="../Vec/VecView.html#VecView">VecView</A>() -> VECOP_VIEW).
<P>
This function is not currently available from Fortran.
