Constructor & Destructor Documentation

◆ F01() [1/2]

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

◆ F01() [2/2]

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
