14.5 vcmul - Vector complex multiplication $xy$

#include <mvec.h>

void vcmul (int n, double complex *z, int incz, const double complex *x, int incx, const double complex *y, int incy);
void vcmulf(int n, float complex *z, int incz, const float complex *x, int incx, const float complex *y, int incy);

Given input vectors $x$ and $y$ and a result vector $z$ , this function computes

z= xy
