dcopy()

subroutine dcopy	(	integer	N,
		double precision, dimension(*)	DX,
		integer	INCX,
		double precision, dimension(*)	DY,
		integer	INCY
	)

DCOPY

Purpose:

    DCOPY copies a vector, x, to a vector, y.
    uses unrolled loops for increments equal to 1.

Parameters

[in]	N	N is INTEGER number of elements in input vector(s)
[in]	DX	DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
[in]	INCX	INCX is INTEGER storage spacing between elements of DX
[out]	DY	DY is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCY ) )
[in]	INCY	INCY is INTEGER storage spacing between elements of DY
