nrf_dsp_stddev_i16()

int32_t nrf_dsp_stddev_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_stddev.h>

Calculate Standard deviation value of a INT16 fixed-point vector.

Parameters

[in]	p_input	Pointer to the input vector
[in]	num	Number of samples in input vector
[in]	p_ctx	Optional pointer to the statistics context, this function will use p_ctx->value.var for calculation if it exist

Returns

int32_t Standard deviation value of the vector
