Sin

Calculates the sine of each element in the source vector.

The function interface declaration is as follows:

HmppResult HMPPS_Sin_32f(const float* src, float* dst, int32_t len);

HmppResult HMPPS_Sin_64f(const double* src, double* dst, int32_t len);

HmppResult HMPPS_Sin_32fc(const Hmpp32fc* src, Hmpp32fc* dst, int32_t len);

HmppResult HMPPS_Sin_64fc(const Hmpp64fc* src, Hmpp64fc* dst, int32_t len);

Parameters

Parameter	Description	Value Range	Input/Output
src	Pointer to the source vector	The value cannot be NULL.	Input
dst	Pointer to the destination vector	The value cannot be NULL.	Output
len	Vector length	(0, INT_MAX]	Input

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

Example

#define  BUFFER_SIZE_T 5
void SinExample()
{
    float src[BUFFER_SIZE_T] = {1, 2.5, 3.3, 1, 5};
    float constValue = 2;
    float dst[BUFFER_SIZE_T];
    HMPPS_Zero_32f(dst, BUFFER_SIZE_T); //Initialize all elements of dst to 0.
    HmppResult result = HMPPS_Sin_32f(src, dst, BUFFER_SIZE_T);
    if (result == HMPP_STS_NO_ERR) {
        printf("dst = ");
        for (int32_t i = 0; i < BUFFER_SIZE_T; i++) {
            printf("%.2f ", dst[i]);
        }
        printf("\n");
    }
}

Output:

dst = 0.84 0.60 -0.16 0.84 -0.96
