DLARGV(l)					)					DLARGV(l)

NAME
       DLARGV  -  generate  a  vector of real plane rotations, determined by elements of the real
       vectors x and y

SYNOPSIS
       SUBROUTINE DLARGV( N, X, INCX, Y, INCY, C, INCC )

	   INTEGER	  INCC, INCX, INCY, N

	   DOUBLE	  PRECISION C( * ), X( * ), Y( * )

PURPOSE
       DLARGV generates a vector of real plane rotations, determined by elements of the real vec-
       tors x and y. For i = 1,2,...,n
	  (  c(i)  s(i) ) ( x(i) ) = ( a(i) )
	  ( -s(i)  c(i) ) ( y(i) ) = (	 0  )

ARGUMENTS
       N       (input) INTEGER
	       The number of plane rotations to be generated.

       X       (input/output) DOUBLE PRECISION array,
	       dimension  (1+(N-1)*INCX) On entry, the vector x.  On exit, x(i) is overwritten by
	       a(i), for i = 1,...,n.

       INCX    (input) INTEGER
	       The increment between elements of X. INCX > 0.

       Y       (input/output) DOUBLE PRECISION array,
	       dimension (1+(N-1)*INCY) On entry, the vector y.  On exit, the sines of the  plane
	       rotations.

       INCY    (input) INTEGER
	       The increment between elements of Y. INCY > 0.

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

       INCC    (input) INTEGER
	       The increment between elements of C. INCC > 0.
