Canberra distance.

Functions

RISCV_DSP_ATTRIBUTE float16_t riscv_canberra_distance_f16 (const float16_t *pA, const float16_t *pB, uint32_t blockSize)

Canberra distance between two vectors.

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

• pA – [in] First vector

• pB – [in] Second vector

• blockSize – [in] vector length

Returns
