◆ RelativeDifference()

double IntensityDataFunctions::RelativeDifference	(	const SimulationResult &	dat,
		const SimulationResult &	ref
	)

Returns sum of relative differences between each pair of elements: (a, b) -> 2*abs(a - b)/(a + b) ( and zero if a-b=0 )

Returns sum of relative differences between each pair of elements: (a, b) -> 2*abs(a - b)/(|a| + |b|) ( and zero if a=b=0 within epsilon )
