v?sinh

Compute the hyperbolic sine of vector elements.

Interface Definition

C interface:

void vssinh(const int len, const float* src, float* dst);

void vdsinh(const int len, const double* src, double* dst);

Fortran interface:

CALL VSSINH(LEN, SRC, DST);

CALL VDSINH(LEN, SRC, DST);

Parameters

Parameter	Type	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	For vssinh, src is of single-precision floating-point type. For vdsinh, src is of double-precision floating-point type.	Input vector src with length len. If the pointer is null, the system prompts a null pointer error.	Input
dst	For vssinh, dst is of single-precision floating-point type. For vdsinh, dst is of double-precision floating-point type.	Output vector dst with length len. If the pointer is null, the system prompts a null pointer error.	Output

Parameter

Type

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

For vssinh, src is of single-precision floating-point type.
For vdsinh, src is of double-precision floating-point type.

Input vector src with length len.

If the pointer is null, the system prompts a null pointer error.

Input

dst

For vssinh, dst is of single-precision floating-point type.
For vdsinh, dst is of double-precision floating-point type.

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 the radian angle x is returned for each operation value.
If the input is +0, the return value is +0.
If the input is -0, the return value is -0.
If the input value of sinhf is greater than 0x1.8p6f, +∞ is returned. If the input value of sinh is greater than 0x1.8p9, +∞ is returned.
If the input value of sinhf is less than -0x1.8p6f, –∞ is returned. If the input value of sinh is less than -0x1.8p9, –∞ is returned.
If the input is ±∞, the return value is ±∞.
If the input is NaN, the return value is NaN.

Examples

C interface:

    int i, len = 4; 
    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); 
    /** 
     *  Output dst: 
     *     0.0  1.1752011936  inf  nan 
     * 
     */

Fortran interface:

    INTEGER :: LEN = 4 
    REAL(4) :: SRC(4)  
    REAL(4) :: DST(4) 
    DATA SRC/1, 2, 3, 4/ 
    CALL VSSINH(LEN, SRC, DST) 
    !  
    ! OUTPUT DST: 
    !     1.17520119, 3.62686041, 10.0178749, 27.2899172
