)

SAXPY

Purpose:
    SAXPY constant times a vector plus a vector.
    uses unrolled loops for increments equal to one.
Parameters
[in]N
          N is INTEGER
         number of elements in input vector(s)
[in]SA
          SA is REAL
           On entry, SA specifies the scalar alpha.
[in]SX
          SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
[in]INCX
          INCX is INTEGER
         storage spacing between elements of SX
[in,out]SY
          SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) )
[in]INCY
          INCY is INTEGER
         storage spacing between elements of SY
