Detailed Description

template<class T, class GridView>
class AMDiS::ConstantGridFunction< T, GridView >

Gridfunction returning a constant value.

A stored constant is return in global and local evaluation of this functor. Maybe used with arithmetic types and vectors/matrices of arithmetic types. It is also allowed to pass a std::reference_wrapper to allow to modify the value after construction.
