Once you have called this routine you can call <A HREF="../KSP/KSPSetOperators.html#KSPSetOperators">KSPSetOperators</A>() on the resulting ksp to provide the operator for the Galerkin problem,
an alternative is to use <A HREF="../PC/PCGalerkinSetComputeSubmatrix.html#PCGalerkinSetComputeSubmatrix">PCGalerkinSetComputeSubmatrix</A>() to provide a routine that computes the submatrix as needed.
