Member Function Documentation

clear()

template<typename VectorType>

virtual void MGSmootherBase< VectorType >::clear ( )

pure virtual

Release matrices.

Implemented in MGSmootherPrecondition< MatrixType, PreconditionerType, VectorType >, MGSmootherRelaxation< MatrixType, RelaxationType, VectorType >, mg::SmootherRelaxation< RelaxationType, VectorType >, MGSmootherIdentity< VectorType >, and MGSmootherBlock< MatrixType, RelaxationType, number >.

smooth()

template<typename VectorType>

virtual void MGSmootherBase< VectorType >::smooth ( const unsigned int  level, VectorType &  u, const VectorType &  rhs  ) const

pure virtual

Smoothing function. This is the function used in multigrid methods.
