Detailed Description

template<typename BlockDiagonalLocalOperator, typename W, typename XView, typename EG, typename LFSU, typename LFSV>
struct Dune::PDELab::impl::BlockDiagonalOperator< BlockDiagonalLocalOperator, W, XView, EG, LFSU, LFSV >

Create ISTL operator that applies a local block diagonal.

This class is similar to the OnTheFlyOperator in the sense that a local operator is used to create an ISTL operator can be used to solve a linear system of equations in a matrix free way.

Where the OnTheFlyOperator takes a grid operator and solves a global system, this class only solves the local block diagonal system.
