       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)

SYNOPSIS

   Functions/Subroutines
       subroutine dlartv (N, X, INCX, Y, INCY, C, S, INCC)
	   DLARTV applies a vector of plane rotations with real cosines and real sines to the elements of a pair of vectors.

Function/Subroutine Documentation
   subroutine dlartv (integerN, double precision, dimension( * )X, integerINCX, double precision, dimension( * )Y, integerINCY, double precision,
       dimension( * )C, double precision, dimension( * )S, integerINCC)
       DLARTV applies a vector of plane rotations with real cosines and real sines to the elements of a pair of vectors.

       Purpose:

	    DLARTV applies a vector of real plane rotations to elements of the
	    real vectors x and y. For i = 1,2,...,n

	       ( x(i) ) := (  c(i)  s(i) ) ( x(i) )
	       ( y(i) )    ( -s(i)  c(i) ) ( y(i) )

       Parameters:
	   N

		     N is INTEGER
		     The number of plane rotations to be applied.

	   X

		     X is DOUBLE PRECISION array,
				    dimension (1+(N-1)*INCX)
		     The vector x.

	   INCX

		     INCX is INTEGER
		     The increment between elements of X. INCX > 0.

	   Y

		     Y is DOUBLE PRECISION array,
				    dimension (1+(N-1)*INCY)
		     The vector y.

	   INCY

		     INCY is INTEGER
		     The increment between elements of Y. INCY > 0.

	   C

		     C is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
		     The cosines of the plane rotations.

	   S

		     S is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
		     The sines of the plane rotations.

	   INCC

		     INCC is INTEGER
		     The increment between elements of C and S. INCC > 0.
