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.

Constructor & Destructor Documentation

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

MGCoarseGridLACIteration< SOLVER, VECTOR >::MGCoarseGridLACIteration

(

)

Default constructor.

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

template<class MATRIX , class PRECOND >

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

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

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

MGCoarseGridLACIteration< SOLVER, VECTOR >::~MGCoarseGridLACIteration

(

)

Destructor freeing the pointers.

Member Function Documentation

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

template<class MATRIX , class PRECOND >

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

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 &

)

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