SYNOPSIS

   Functions/Subroutines
       subroutine dcopy (N, DX, INCX, DY, INCY)
	   DCOPY

Function/Subroutine Documentation
   subroutine dcopy (integerN, double precision, dimension(*)DX, integerINCX, double precision, dimension(*)DY, integerINCY)
       DCOPY Purpose:

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

NAME

       drotm.f -

SYNOPSIS

   Functions/Subroutines
       subroutine drotm (N, DX, INCX, DY, INCY, DPARAM)
	   DROTM

Function/Subroutine Documentation
   subroutine drotm (integerN, double precision, dimension(*)DX, integerINCX, double precision, dimension(*)DY, integerINCY, double precision,
       dimension(5)DPARAM)
       DROTM Purpose:

	       APPLY THE MODIFIED GIVENS TRANSFORMATION, H, TO THE 2 BY N MATRIX

	       (DX**T) , WHERE **T INDICATES TRANSPOSE. THE ELEMENTS OF DX ARE IN
	       (DY**T)

	       DX(LX+I*INCX), I = 0 TO N-1, WHERE LX = 1 IF INCX .GE. 0, ELSE
	       LX = (-INCX)*N, AND SIMILARLY FOR SY USING LY AND INCY.
	       WITH DPARAM(1)=DFLAG, H HAS ONE OF THE FOLLOWING FORMS..

	       DFLAG=-1.D0     DFLAG=0.D0	 DFLAG=1.D0	DFLAG=-2.D0

		 (DH11	DH12)	 (1.D0	DH12)	 (DH11	1.D0)	 (1.D0	0.D0)
	       H=(	    )	 (	    )	 (	    )	 (	    )
		 (DH21	DH22),	 (DH21	1.D0),	 (-1.D0 DH22),	 (0.D0	1.D0).
	       SEE DROTMG FOR A DESCRIPTION OF DATA STORAGE IN DPARAM.

		DPARAM(1)=DFLAG
		DPARAM(2)=DH11
		DPARAM(3)=DH21
		DPARAM(4)=DH12
		DPARAM(5)=DH22
