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

Calculate Sum value of a INT32 fixed-point vector ​​using values ​​in increments of 'stride'.

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
[out]	p_ctx	Optional pointer to the statistics context, the calculated value of sum will be written to context for further use

Returns

int64_t Sum value of the vector
