NAME

       LAPACK-3  -  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

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
