v?sinh
Interface Definition
C interface:
void vssinh(const int len, const float* src, float* dst);
void vdsinh(const int len, const double* src, double* dst);
void vcsinh(const int len, const float complex *src, float complex *dst);
void vzsinh(const int len, const double complex *src, double complex *dst);
Fortran interface:
CALL VSSINH(LEN, SRC, DST);
CALL VDSINH(LEN, SRC, DST);

Description |
Input/Output |
|---|---|---|---|
len |
Integer |
Number of elements in the input vector. If len ≤ 0, the system displays a message indicating that the value of len is invalid. |
Input |
src |
|
Input vector src with length len. If the pointer is null, the system prompts a null pointer error. |
Input |
dst |
|
Output vector dst with length len. If the pointer is null, the system prompts a null pointer error. |
Output |
Return Value
- The hyperbolic sine y of radian angle x is returned for each operation value, that is, y = sinh(x). y ∈ [-∞, +∞]
- For special values, see the following table.

Examples
C interface:

float src[len] = {0.0f, 1.0f, inf, nan};
float* dst = (float*)malloc(sizeof(float) * len);
if (dst == NULL) {
printf("Malloc Failed!\n");
return 0;
}
vssinh(len, src, dst);
