See the file include/petscmat.h for a complete list of matrix
operations, which all have the form MATOP_<OPERATION>, where
<OPERATION> is the name (in all capital letters) of the
user interface routine (e.g., <A HREF="../Mat/MatMult.html#MatMult">MatMult</A>() -> MATOP_MULT).
<P>
This routine is distinct from <A HREF="../Mat/MatShellGetOperation.html#MatShellGetOperation">MatShellGetOperation</A>() in that it can be called on any matrix type.
