v?pow2o3

Compute an input vector raised to the power of 2/3.

Interface Definition

C interface:

void vspow2o3(const int len, const float* src, float* dst);

void vdpow2o3(const int len, const double* src, double* 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	Single-precision floating-point type for vspow2o3 Double-precision floating-point type for vdpow2o3	Input vector src with length len. If the pointer is null, the system prompts a null pointer error.	Input
dst	Single-precision floating-point type for vspow2o3 Double-precision floating-point type for vdpow2o3	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

Single-precision floating-point type for vspow2o3
Double-precision floating-point type for vdpow2o3

Input vector src with length len.

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

Input

dst

Single-precision floating-point type for vspow2o3
Double-precision floating-point type for vdpow2o3

Output vector dst with length len.

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

Output

Return Value

Input Value (src)	Output Value (dst)
+0	+0
-0	+0
+inf	+inf
-inf	+inf
nan	nan

Examples

C interface:

    int i, len = 4; 
    float src[len] = {0.0f, 2.0f, inf, nan}; 
    float* dst = (float*)malloc(sizeof(float) * len); 
    if (dst == NULL) { 
        printf("Malloc Failed!\n"); 
        return 0; 
    } 
    vspow2o3(len, src, dst); 
    /** 
     *  Output dst: 
     *     0.0 1.587401 inf  nan 
     * 
     */
