		integer	incx,
		double precision, dimension(*)	dy,
		integer	incy )

DAXPY

Purpose:

!>
!>    DAXPY 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]	DA	!> DA is DOUBLE PRECISION !> On entry, DA specifies the scalar alpha. !>
[in]	DX	!> DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) ) !>
[in]	INCX	!> INCX is INTEGER !> storage spacing between elements of DX !>
[in,out]	DY	!> DY is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCY ) ) !>
[in]	INCY	!> INCY is INTEGER !> storage spacing between elements of DY !>
