Detailed Description

template<typename GFS, typename V, int diffOrder = 0>
class Dune::PDELab::DiscreteGridViewFunction< GFS, V, diffOrder >

A discrete function defined over a GridFunctionSpace.

This class models the GridViewFunction concept of dune-functions. It represents a global function. The user can obtain a GridViewFunction::LocalFunction via localfunction(globalfunction) and use this to evaluate in local coordinates.

Note: it is going to replace the old interfaces based on GridFunctionInterface and FunctionInterface

Template Parameters

GFS	the GridFunctionSpace this function is defined on. GFS yields information on the particular basis.
V	the storage container for the coefficients of the discrete function.
