nrf_dsp_kur_i16()

int32_t nrf_dsp_kur_i16	(	const int16_t *	p_input,
		uint16_t	num,
		nrf_dsp_stat_ctx_i16_t *	p_ctx )

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

Calculate Kurtosis of a INT16 vector.

Note

Can return NRF_DSP_ZERO_DIV_FLAG if NRF_DSP_ENABLE_RUNTIME_CHECKS is defined.

Parameters

[in]	p_input	Pointer to the input vector
[in]	num	Number of samples in input vector
[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

Returns

int32_t Kurtosis value in integer format, not real value but with high correlation to floating-point kurtosis
