Chapter 12 VMATH 817
The cube root of the elements of a vector vsCbrt, vdCbrt
Name vsCbrt, vdCbrt
The cube root of the elements of a vector
Purpose vsCbrt and vdCbrt calculate the cube root function of vector elements:
y[i] = cbrt(a[i]), for 0 <= i <= n-1
Usage VMATH:
#include <vmath.h>
void vsCbrt (int n, const float a[ ], float y [ ] ) ;
void vdCbrt (int n, const double a [ ], double y [ ] ) ;
VMATH8:
#include <vmath8.h>
void vsCbrt (long long n, const float a[ ], float y [ ] ) ;
void vdCbrt (long long n, const double a [ ], double y [ ] ) ;
Input n Number of elements to be calculated.
a Array of length at least n, specifying the input vector.
Output y Array of length at least n, specifying the output vector.
