Detailed Description

template<typename X, typename Y, typename GO>
class Dune::PDELab::OnTheFlyOperator< X, Y, GO >

Create ISTL operator from a grid operator object

In the nonlinear case the operator need to be linearized by setting a linearization point before it can be used.

Template Parameters

X	Trial vector.
Y	Test vector.
GO	Grid operator that implements the jacobian apply
