Function

vvrec

Calculates the reciprocal of each element in an array of double-precision values.

Declaration

void vvrec(double *, const double *, const int *);

Parameters

parameter 1: The output array, y.
parameter 2: The input array, x.
parameter 3: The number of elements in the arrays.

Discussion

The following code shows an example of using vvrec.

double x[] = {2, 4, 8, 16};
double y[4];
int n = 4;
 
vvrec(y, x, &n);
 
NSLog(@"y: [%lf, %lf, %lf, %lf]", y[0], y[1], y[2], y[3]);
