Functions

void arm_min_f32 (float32_t *pSrc, uint32_t blockSize, float32_t *pResult, uint32_t *pIndex)
 Minimum value of a floating-point vector.
void arm_min_q15 (q15_t *pSrc, uint32_t blockSize, q15_t *pResult, uint32_t *pIndex)
 Minimum value of a Q15 vector.
void arm_min_q31 (q31_t *pSrc, uint32_t blockSize, q31_t *pResult, uint32_t *pIndex)
 Minimum value of a Q31 vector.
void arm_min_q7 (q7_t *pSrc, uint32_t blockSize, q7_t *pResult, uint32_t *pIndex)
 Minimum value of a Q7 vector.

Detailed Description

Computes the minimum value of an array of data.

The function returns both the minimum value and its position within the array. There are separate functions for floating-point, Q31, Q15, and Q7 data types.
