void
cublasSaxpy (int n, float alpha, const float *x, int incx, float *y,
int incy)

multiplies single precision vector x by single precision scalar alpha
and adds the result to single precision vector y; that is, it overwrites
single precision y with single precision alpha * x + y. For i = 0 to n - 1,
it replaces y[ly + i * incy] with alpha * x[lx + i * incx] + y[ly + i *
incy], where lx = 1 if incx >= 0, else lx = 1 +(1 - n) * incx, and ly is
defined in a similar way using incy.

Input
-----
n      number of elements in input vectors
alpha  single precision scalar multiplier
x      single precision vector with n elements
incx   storage spacing between elements of x
y      single precision vector with n elements
incy   storage spacing between elements of y

Output
------
y      single precision result (unchanged if n <= 0)
