Chapter 12 VMATH 825
The reciprocal cube root of the elements of a vector vsInvCbrt, vdInvCbrt
Name vsInvCbrt, vdInvCbrt
The reciprocal cube root of the elements of a vector
Purpose vsInvCbrt and vdInvCbrt calculate the reciprocal cube root function of vector
elements:
y[i] = 1.0/cbrt(a[i]), for 0 <= i <= n-1
Usage VMATH:
#include <vmath.h>
void vsInvCbrt (int n, const float a[ ], float y [ ] ) ;
void vdInvCbrt (int n, const double a [ ], double y [ ] ) ;
VMATH8:
#include <vmath8.h>
void vsInvCbrt (long long n, const float a[ ], float y [ ] ) ;
void vdInvCbrt (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.
