Constructor & Destructor Documentation

template<class NodeX , class NodeY >

cluster::F01< NodeX, NodeY >::F01	(	const Tree< NodeX > &	treeX,
		const Tree< NodeY > &	treeY,
		const ExpansionF< FX > &	exp,
		concepts::Real	eta,
		uint	minsz
	)

Constructor.

Different cluster trees for ansatz and test space are possible. The cluster approximation is non symmetric, i.e., CG not applicable.

Parameters:

treeX	Cluster tree
treeY	Cluster tree
exp	Kernel expansion
eta	Far field coefficient
minsz	Minimal size for to clusters to belong to the far field

template<class NodeX , class NodeY >

cluster::F01< NodeX, NodeY >::F01	(	const Tree< NodeX > &	tree,
		const ExpansionF< FX > &	exp,
		concepts::Real	eta,
		uint	minsz
	)

Constructor.

Same cluster tree for ansatz and test space, i.e. for symmetric stiffness matrices the cluster approximation will also be symmetric.

Parameters:

tree	Cluster tree
exp	Kernel expansion
eta	Far field coefficient
minsz	Minimal size for to clusters to belong to the far field
