Detailed Description

template<class NodeX, class NodeY>
class cluster::F03< NodeX, NodeY >

Far field matrix F.

Expansion order m, $\eta^m/(c-r)^s < \epsilon$ , at most far field entries are saved. Stores just a few far field values and computes the other one on the fly.

Parameters

NodeX	Cluster node
NodeY	Cluster node
