◆ init_H2Matrix()

template<typename ScalarT >

template<typename Derived >

void Eigen::H2Matrix< ScalarT >::init_H2Matrix	(	const Derived &	linOp,
		const Bembel::AnsatzSpace< Derived > &	ansatz_space,
		int	number_of_points = `9`
	)

inline

Assemble H2-Matrix for linear operator linOp and AnsatzSpace ansatz_space with number_of_points interpolation points in one direction of the unit square (standard is number_of_points=9)

Todo:: Juergen Discuss with Michael where to initialize the parameters: min_cluster_level depends on number_of_points, but this is not implemented yet, also, what do the parameter mean?
