Detailed Description

template<typename VectorType>
class MGSmootherIdentity< VectorType >

Smoother doing nothing. This class is not useful for many applications other than for testing some multigrid procedures. Also some applications might get convergence without smoothing and then this class brings you the cheapest possible multigrid.

Member Function Documentation

smooth()

template<typename VectorType >

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

virtual

Implementation of the interface for Multigrid. This function does nothing, which by comparison with the definition of this function means that the the smoothing operator equals the null operator.

Implements MGSmootherBase< VectorType >.

clear()

template<typename VectorType >

virtual void MGSmootherIdentity< VectorType >::clear ( )

virtual

Release matrices.

Implements MGSmootherBase< VectorType >.
