eval()

double sgpp::combigrid::OperationEvalCombinationGrid::eval	(	const std::vector< base::DataVector > &	surpluses,
		const base::DataVector &	point
	)

Evaluate a combination grid function at one point.

Parameters

surpluses	coefficients for the basis functions (may be nodal/hierarchical), every vector corresponds to one full grid (the order of DataVector entries is given by IndexVectorRange)
point	point at which to evaluate the combination grid function

Returns

value of the combination grid function at the given point
