v?cbrt

Compute the cube root of the input vector.

Interface Definition

C interface:

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

void vdcbrt(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, an invalid parameter error is reported and the function returns.	Input
src	Single-precision floating-point type for vscbrt Double-precision floating-point type for vdcbrt	Input vector src with length len. If the pointer is null, a null pointer error is reported and the function returns.	Input
dst	Single-precision floating-point type for vscbrt Double-precision floating-point type for vdcbrt	Output vector dst with length len. If the pointer is null, a null pointer error is reported and the function returns.	Output

Parameter

Type

Description

Input/Output

len

Integer

Number of elements in the input vector.

If len ≤ 0, an invalid parameter error is reported and the function returns.

Input

src

Single-precision floating-point type for vscbrt
Double-precision floating-point type for vdcbrt

Input vector src with length len.

If the pointer is null, a null pointer error is reported and the function returns.

Input

dst

Single-precision floating-point type for vscbrt
Double-precision floating-point type for vdcbrt

Output vector dst with length len.

If the pointer is null, a null pointer error is reported and the function returns.

Output

Return Value

The cube root of each input value is returned.

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

Examples

C interface:

    #define N 4
    const float src[N] = {-1.0f, 27.0f, -INFINITY, NAN};
    float dst[N] = {0};

    vscbrt(N, src, dst);

 
    /** 
     *  input :  -1.000   27.000      -inf      nan 
     *  output:  -1.000    3.000      -inf      nan
     *
