Detailed Description

template<class Scalar, class LocalOrdinal, class GlobalOrdinal, class Node>
class MueLu::MatlabSmoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Class that encapsulates Matlab smoothers.

This class creates an Matlab preconditioner factory. The factory creates a smoother based on the type and ParameterList passed into the constructor. See the constructor for more information.

void MueLu::MatlabSmoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >::SetParameterList ( const Teuchos::ParameterList & paramList )

virtual

Set parameters from a parameter list and return with default values.

Reimplemented from MueLu::ParameterListAcceptorImpl.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >

void MueLu::MatlabSmoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Setup ( Level & currentLevel )

virtual

Set up the smoother.

This creates the underlying Matlab smoother object, copies any parameter list options supplied to the constructor to the Matlab object, and computes the preconditioner.

TODO The eigenvalue estimate should come from A_, not the Matlab parameter list.

Implements MueLu::SmootherPrototype< Scalar, LocalOrdinal, GlobalOrdinal, Node >.

void MueLu::MatlabSmoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Apply	(	MultiVector &	X,
		const MultiVector &	B,
		bool	InitialGuessIsZero = `false`
	)		const

virtual

Apply the preconditioner.

Solves the linear system AX=B using the constructed smoother.

Parameters

X	initial guess
B	right-hand side
InitialGuessIsZero	(optional) If false, some work can be avoided. Whether this actually saves any work depends on the underlying Matlab implementation.
