11.8 vsdiv - Vector scalar division x/α

#include <mvec.h>

void vsdiv (int n, double *y, int incy, const double *x, int incx, double a);
void vsdivf(int n, float *y, int incy, const float *x, int incx, float a);

Given an input vector x  and a scalar constant α and a result vector y  , this function computes:

y= x/α
