SAXPY

Purpose:

    SAXPY constant times a vector plus a vector.
    uses unrolled loops for increments equal to one.
Parameters:

N

          N is INTEGER
         number of elements in input vector(s)

SA

          SA is REAL
           On entry, SA specifies the scalar alpha.

SX

          SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )

INCX

          INCX is INTEGER
         storage spacing between elements of SX

SY

          SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) )
