#include <include/nrf_edgeai/dsp/statistic/nrf_dsp_moments.h>

Calculate 3 higher statistical moments(Variance, Skewness, Kurtosis) of a floating-point vector.

Parameters

[in]	p_input	Pointer to the input vector
[in]	num	Number of samples with 'stride' in input vector
[in]	stride	Vector element offset stride
[in,out]	p_ctx	Optional pointer to the statistics context, this function will use p_ctx->value.sum and/or p_ctx->value.var for calculation if it exist, the calculated value of variance will be written to context for further use
[out]	p_m	Pointer to the moments container nrf_dsp_moments_f32_t
