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
XTrial vector.
YTest vector.
GOGrid operator that implements the jacobian apply

◆ setLinearizationPoint()

template<typename X , typename Y , typename GO >
void Dune::PDELab::OnTheFlyOperator< X, Y, GO >::setLinearizationPoint ( const X &  u)
inline

Set linearization point. Must be called before apply() and applyscaleadd() for nonlinear problems.
