This can be called if you have precomputed the nonzero structure of the
matrix and want to provide it to the matrix object to improve the performance
of the <A HREF="../Mat/MatSetValues.html#MatSetValues">MatSetValues</A>() operation.
<P>
You MUST have set the correct numbers of nonzeros per row in the call to
<A HREF="../Mat/MatCreateSeqBAIJ.html#MatCreateSeqBAIJ">MatCreateSeqBAIJ</A>(), and the columns indices MUST be sorted.
<P>
MUST be called before any calls to <A HREF="../Mat/MatSetValues.html#MatSetValues">MatSetValues</A>();
