PURPOSE
  CLAR2V - applie a vector of complex plane rotations with real cosines from
  both sides to a sequence of 2-by-2 complex Hermitian matrices,

SYNTAX
  SUBROUTINE CLAR2V( N, X, Y, Z, INCX, C, S, INCC )

      INTEGER	     INCC, INCX, N

      REAL	     C( * )

      COMPLEX	     S( * ), X( * ), Y( * ), Z( * )

DESCRIPTION
  CLAR2V applies a vector of complex plane rotations with real cosines from
  both sides to a sequence of 2-by-2 complex Hermitian matrices, defined by
  the elements of the vectors x, y and z. For i = 1,2,...,n

     (	     x(i)  z(i) ) :=
     ( conjg(z(i)) y(i) )

       (  c(i) conjg(s(i)) ) (	     x(i)  z(i) ) ( c(i) -conjg(s(i)) )
       ( -s(i)	     c(i)  ) ( conjg(z(i)) y(i) ) ( s(i)	c(i)  )

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

  X	  (input/output) COMPLEX array, dimension (1+(N-1)*INCX)
	  The vector x; the elements of x are assumed to be real.

  Y	  (input/output) COMPLEX array, dimension (1+(N-1)*INCX)
	  The vector y; the elements of y are assumed to be real.

  Z	  (input/output) COMPLEX array, dimension (1+(N-1)*INCX)
	  The vector z.

  INCX	  (input) INTEGER
	  The increment between elements of X, Y and Z. INCX > 0.

	  The cosines of the plane rotations.

  S	  (input) COMPLEX array, dimension (1+(N-1)*INCC)
	  The sines of the plane rotations.

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