Detailed Description

template<class DiscreteFunctionSpace, class Traits>
class Dune::ACFem::LocalLinearFunctional< DiscreteFunctionSpace, Traits >

Interface or better: factory for local functionals.

Member Function Documentation

coefficients() [1/2]

template<class DiscreteFunctionSpace , class Traits >

template<class LocalFunction >

void Dune::ACFem::LocalLinearFunctional< DiscreteFunctionSpace, Traits >::coefficients ( const RangeType &  c, LocalFunction &  coeffs  ) const

inline

Compute the basis representation, which means: do the assembling stuff.

To support expression templates this version accecpts a scalar factor and computes

\[ <c\,\Psi|_E, \phi^k|_E> \]

for all local basis functions \(\phi^k|_E\)

coefficients() [2/2]

template<class DiscreteFunctionSpace , class Traits >

template<class LocalFunction >

void Dune::ACFem::LocalLinearFunctional< DiscreteFunctionSpace, Traits >::coefficients ( LocalFunction &  coeffs ) const

inline

Compute the basis representation, which means: do the assembling stuff.

This has to compute

\[ <\Psi|_E, \phi^k|_E> \]

for all local basis functions \(\phi^k|_E\)
