compute_std_dev_statistic()

std::vector< double > MayaFlux::Yantra::compute_std_dev_statistic	(	std::span< const double >	data,
		const size_t	num_windows,
		const uint32_t	hop_size,
		const uint32_t	window_size,

	)

Compute standard deviation statistic using zero-copy processing.

This function computes the standard deviation for a given data span. It calculates the square root of variance in each window.

Parameters

data	Input data span
num_windows	Number of windows to process
hop_size	Hop size for windowing
window_size	Size of each window
sample_variance	If true, use sample variance (N-1), else population (N)

Returns

Vector of standard deviation values
