Detailed Description

template<class VECTOR>
class MGSmootherIdentity< VECTOR >

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.

template<class VECTOR >
virtual void MGSmootherIdentity< VECTOR >::smooth ( const unsigned int  level,
VECTOR &  u,
const VECTOR &  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< VECTOR >.

template<class VECTOR >
virtual void MGSmootherIdentity< VECTOR >::clear (  ) [virtual]

Release matrices.
