CLAR2V(3F)							    CLAR2V(3F)

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

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

	 INTEGER	INCC, INCX, N

	 REAL		C( * )

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

PURPOSE
     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.

     C	     (input) REAL array, dimension (1+(N-1)*INCC)
	     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.
