NAME
       SRC/dlar2v.f

SYNOPSIS
   Functions/Subroutines
       subroutine dlar2v (n, x, y, z, incx, c, s, incc)
           DLAR2V applies a vector of plane rotations with real cosines and
           real sines from both sides to a sequence of 2-by-2
           symmetric/Hermitian matrices.

Function/Subroutine Documentation
   subroutine dlar2v (integer n, double precision, dimension( * ) x, double
       precision, dimension( * ) y, double precision, dimension( * ) z,
       integer incx, double precision, dimension( * ) c, double precision,
       dimension( * ) s, integer incc)
       DLAR2V applies a vector of plane rotations with real cosines and real
       sines from both sides to a sequence of 2-by-2 symmetric/Hermitian
       matrices.

       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) )
