Description

Canberra distance

Function Documentation

arm_canberra_distance_f16()

float16_t arm_canberra_distance_f16	(	const float16_t *	pA,
		const float16_t *	pB,
		uint32_t	blockSize
	)

This function may divide by zero when samples pA[i] and pB[i] are both zero. The result of the computation will be correct. So the division per zero may be ignored.

Parameters

[in]	pA	First vector
[in]	pB	Second vector
[in]	blockSize	vector length

Returns

distance

arm_canberra_distance_f32()

float32_t arm_canberra_distance_f32	(	const float32_t *	pA,
		const float32_t *	pB,
		uint32_t	blockSize
	)

This function may divide by zero when samples pA[i] and pB[i] are both zero. The result of the computation will be correct. So the division per zero may be ignored.

Parameters

[in]	pA	First vector
[in]	pB	Second vector
[in]	blockSize	vector length

Returns

distance
