Detailed Description

template<typename DGBF>
class Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::LocalFunction

local function evaluating the derivative in reference coordinates

Note that the function returns the derivative with respect to global coordinates even when the point is given in reference coordinates on an element.

Member Function Documentation

bind()

template<typename DGBF >

void Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::LocalFunction::bind ( const Element &  element )

inline

Bind LocalFunction to grid element.

You must call this method before operator() and after changes to the coefficient vector.

operator()()

template<typename DGBF >

Range Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::LocalFunction::operator() ( const Domain &  x ) const

inline

Evaluate this local-function in coordinates x in the bound element.

The result of this method is undefined if you did not call bind() beforehand or changed the coefficient vector after the last call to bind(). In the latter case you have to call bind() again in order to make operator() usable.

Note that the function returns the derivative with respect to global coordinates even when the point is given in reference coordinates on an element.
