Detailed Description

template<class SOLVER, class VECTOR = Vector<double>>
class MGCoarseGridLACIteration< SOLVER, VECTOR >

Coarse grid solver using LAC iterative methods. This is a little wrapper, transforming a triplet of iterative solver, matrix and preconditioner into a coarse grid solver.

The type of the matrix (i.e. the template parameter MATRIX) should be derived from Subscriptor to allow for the use of a smart pointer to it.

MGCoarseGridLACIteration< SOLVER, VECTOR >::MGCoarseGridLACIteration	(	SOLVER &	,
		const MATRIX &	,
		const PRECOND &
	)			[inline]

Constructor. Store solver, matrix and preconditioning method for later use.

template<class SOLVER , class VECTOR = Vector<double>>

template<class MATRIX , class PRECOND >

void MGCoarseGridLACIteration< SOLVER, VECTOR >::initialize	(	SOLVER &	,
		const MATRIX &	,
		const PRECOND &
	)			[inline]

Initialize new data.

template<class SOLVER , class VECTOR = Vector<double>>

void MGCoarseGridLACIteration< SOLVER, VECTOR >::clear

(

)

Clear all pointers.

template<class SOLVER , class VECTOR = Vector<double>>

void MGCoarseGridLACIteration< SOLVER, VECTOR >::operator()	(	const unsigned int	level,
		VECTOR &	dst,
		const VECTOR &	src
	)			const [virtual]

Implementation of the abstract function. Calls the solver method with matrix, vectors and preconditioner.

Implements MGCoarseGridBase< VECTOR >.

template<class SOLVER , class VECTOR = Vector<double>>

template<class MATRIX >

void MGCoarseGridLACIteration< SOLVER, VECTOR >::set_matrix

(

const MATRIX &

)

[inline]

Sets the matrix. This gives the possibility to replace the matrix that was given to the constructor by a new matrix.
