void
sscal (int n, float alpha, float *x, int incx)

replaces single precision vector x with single precision alpha * x. For i
= 0 to n - 1, it replaces x[ix + i * incx] with alpha * x[ix + i * incx],
where ix = 1 if incx >= 0, else ix = 1 + (1 - n) * incx.

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

Output
------
x      single precision result (unchanged if n <= 0 or incx <= 0)
