Min

Obtains the minimum value in a vector.

The function interface declaration is as follows:

  • Operations on integers:

    HmppResult HMPPS_Min_16s(const int16_t *src, int32_t len, int16_t *min);

    HmppResult HMPPS_Min_32s(const int32_t *src, int32_t len, int32_t *min);

  • Operations on floating-point numbers:

    HmppResult HMPPS_Min_32f(const float *src, int32_t len, float *min);

    HmppResult HMPPS_Min_64f(const double *src, int32_t len, double *min);

Parameters

Parameter

Description

Value Range

Input/Output

src

Pointer to the source vector

The value cannot be NULL.

Input

len

Vector length

(0, INT_MAX]

Input

min

Pointer to the minimum value

The value cannot be NULL.

Output

Return Value

  • Success: HMPP_STS_NO_ERR
  • Failure: An error code is returned.

Error Codes

Error Code

Description

HMPP_STS_NULL_PTR_ERR

The value of src or min is NULL.

HMPP_STS_SIZE_ERR

The value of len is less than or equal to 0.

Example

#define BUFFER_SIZE_T 10

void MinExample(void)
{
    int16_t src[BUFFER_SIZE_T] = {3, 6, 2, 8, 3, 15, 56, 31, 1, 23};
    int16_t min;

    HmppResult result = HMPPS_Min_16s(src, BUFFER_SIZE_T, &min);
    printf("result = %d  ", result);
    if (result != HMPP_STS_NO_ERR) {
        return;
    }
    printf("min = %d\n", min);
}

Output:

result = 0  min = 1
