NAME
       SRC/zlar2v.f

SYNOPSIS
   Functions/Subroutines
       subroutine zlar2v (n, x, y, z, incx, c, s, incc)
           ZLAR2V applies a vector of plane rotations with real cosines and
           complex sines from both sides to a sequence of 2-by-2
           symmetric/Hermitian matrices.

Function/Subroutine Documentation
   subroutine zlar2v (integer n, complex*16, dimension( * ) x, complex*16,
       dimension( * ) y, complex*16, dimension( * ) z, integer incx, double
       precision, dimension( * ) c, complex*16, dimension( * ) s, integer
       incc)
       ZLAR2V applies a vector of plane rotations with real cosines and
       complex sines from both sides to a sequence of 2-by-2
       symmetric/Hermitian matrices.

       Purpose:


            ZLAR2V 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)  )
