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