Declaration
void vvpow(double *, const double *, const double *, const int *);
Parameters
parameter 1The output array, z.
parameter 2The exponent input array, y.
parameter 3The base input array, x.
parameter 4The number of elements in the arrays.
Discussion
The following code shows an example of using vvpow:
double x[] = {3, 2, 10, 6};
double y[] = {2, 4, 3, 2};
double z[4];
int n = 4;
vvpow(z, y, x, &n);
NSLog(@"z: [%lf, %lf, %lf, %lf]", z[0], z[1], z[2], z[3]);
The following special values of x and y produce the given value of z:
x (base) | y (exponent) | z (result) |
|---|---|---|
