Detailed Description

Class whose methods are called by Ahmed during assembly in the ACA mode.

Member Function Documentation

template<typename BasisFunctionType , typename ResultType >

void Bempp::PotentialOperatorAcaAssemblyHelper< BasisFunctionType, ResultType >::cmpbl	(	unsigned	b1,
		unsigned	n1,
		unsigned	b2,
		unsigned	n2,
		AhmedResultType *	data,
		const cluster *	c1 = `0`,
		const cluster *	c2 = `0`,
		bool	countAccessedEntries = `true`
	)		const

Evaluate entries of a general block.

Store the entries of the block defined by b1, n1, b2, n2 (in permuted ordering) in data.

template<typename BasisFunctionType , typename ResultType >

void Bempp::PotentialOperatorAcaAssemblyHelper< BasisFunctionType, ResultType >::cmpblsym	(	unsigned	b1,
		unsigned	n1,
		AhmedResultType *	data,
		const cluster *	c1 = `0`,
		bool	countAccessedEntries = `true`
	)		const

Evaluate entries of a symmetric block.

Store the upper part of the (symmetric) block defined by b1, n1, b1, n1 (in permuted ordering) columnwise in data.
