This can be called if you will be provided the matrix row by row (from row zero) with sorted column indices for each row.
Simply call <A HREF="../Mat/MatSetValues.html#MatSetValues">MatSetValues</A>() after this call to provide the matrix entries in the usual manner. This matrix may be used
as always with multiple matrix assemblies.
