slice()

std::vector< double > MayaFlux::Kinesis::Discrete::slice	(	std::span< const double >	data,
		double	start_ratio,
		double	end_ratio
	)

Extract a contiguous slice by ratio, returning a new vector.

Parameters

data	Source span
start_ratio	Normalised start position [0, 1]
end_ratio	Normalised end position [0, 1], must be > start_ratio

Returns

Slice data; empty if parameters are degenerate
