17.4 vcpows - Vector complex power scalar exponent $xy$

#include <mvec.h> 
 
void vcpows (int n, double complex *restrict z, int incz, const double complex *restrict x, 
             int incx, double complex y); 
void vcpowsf(int n, float complex *restrict z, int incz, const float complex *restrict x, 
             int incx, float complex y); 
 
void vcpows_64 (long n, double complex *restrict z, long incz, const double complex *restrict x, 
                long incx, double complex y); 
void vcpowsf_64(long n, float complex *restrict z, long incz, const float complex *restrict x, 
                long incx, float complex y);

Given an input vectors $x$ and a scalar value $y$ as well as a result vector $z$ , this function computes:

z= xy

17.4.1 Parameters

N - INTEGER: ENTRY: Number of elements of $x$ and $y$ .
CONSTRAINT: $n ≥1$ .
z - ARRAY OF COMPLEX: EXIT: Result vector $z$ .
CONSTRAINT: Must contain $n× incz$ elements.
CONSTRAINT: Must not overlap with array $x$ .
INCZ - INTEGER: ENTRY: Stride for the vector $z$ .
CONSTRAINT: $incz̸= 0$ .
BEHAVIOR: A negative stride will traverse the array in reverse.
X - ARRAY OF COMPLEX: ENTRY: Input vector $x$ .
CONSTRAINT: Must contain $n× incx$ elements.
CONSTRAINT: Must not overlap with array $z$ .
INCX - INTEGER: ENTRY: Stride for the vector $x$ .
CONSTRAINT: $incx̸= 0$ .
BEHAVIOR: A negative stride will traverse the array in reverse.
Y - COMPLEX: ENTRY: Exponentiation value $y$ .
