zero_crossing_rate() [2/2]

MAYAFLUX_API double MayaFlux::zero_crossing_rate	(	const std::vector< double > &	data,
		size_t	window_size = 0
	)

Calculate zero crossing rate for single-channel data.

Parameters

data	Input signal data
window_size	Analysis window size (0 = whole signal)

Returns

Zero crossing rate (crossings per sample)
