***DESCRIPTION
B L A S Subprogram
Description of Parameters
--Input--
N number of elements in input vector(s)
DX double precision vector with N elements
INCX storage spacing between elements of DX
DY double precision vector with N elements
INCY storage spacing between elements of DY
--Output--
DY copy of vector DX (unchanged if N .LE. 0)
Copy double precision DX to double precision DY.
For I = 0 to N-1, copy DX(LX+I*INCX) to DY(LY+I*INCY),
where LX = 1 if INCX .GE. 0, else LX = 1+(1-N)*INCX, and LY is
defined in a similar way using INCY.
