NAME
       DLAR2V  -  applie a vector of real plane rotations from both sides to a sequence of 2-by-2 real symmetric matrices, defined by the elements
       of the vectors x, y and z

SYNOPSIS
       SUBROUTINE DLAR2V( N, X, Y, Z, INCX, C, S, INCC )

	   INTEGER	  INCC, INCX, N

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

PURPOSE
       DLAR2V applies a vector of real plane rotations from both sides to a sequence of 2-by-2 real symmetric matrices, defined by the elements of
       the vectors x, y and z. For i = 1,2,...,n
	  ( x(i)  z(i) ) := (  c(i)  s(i) ) ( x(i)  z(i) ) ( c(i) -s(i) )
	  ( z(i)  y(i) )    ( -s(i)  c(i) ) ( z(i)  y(i) ) ( s(i)  c(i) )

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

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

       Y       (input/output) DOUBLE PRECISION array,
	       dimension (1+(N-1)*INCX) The vector y.

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

       S       (input) DOUBLE PRECISION 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.
