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)  )

N

          N is INTEGER


          The number of plane rotations to be applied.

X

          X is COMPLEX array, dimension (1+(N-1)*INCX)


          The vector x; the elements of x are assumed to be real.

Y

          Y is COMPLEX array, dimension (1+(N-1)*INCX)


          The vector y; the elements of y are assumed to be real.

Z

          Z is COMPLEX array, dimension (1+(N-1)*INCX)


          The vector z.

INCX

          INCX is INTEGER


          The increment between elements of X, Y and Z. INCX > 0.

C

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


          The cosines of the plane rotations.

S

          S is COMPLEX array, dimension (1+(N-1)*INCC)


          The sines of the plane rotations.

INCC

          INCC is INTEGER


          The increment between elements of C and S. INCC > 0.
