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 !>
