subroutine clartv (n, x, incx, y, incy, c, s, incc)
CLARTV applies a vector of plane rotations with real cosines and complex sines to the elements of a pair of vectors.

CLARTV applies a vector of plane rotations with real cosines and complex sines to the elements of a pair of vectors.  

Purpose:

 CLARTV applies a vector of complex plane rotations with real cosines
 to elements of the complex vectors x and y. For i = 1,2,...,n

    ( x(i) ) := (        c(i)   s(i) ) ( x(i) )
    ( y(i) )    ( -conjg(s(i))  c(i) ) ( y(i) )

Parameters

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.

INCX

          INCX is INTEGER
          The increment between elements of X. INCX > 0.

Y

          Y is COMPLEX array, dimension (1+(N-1)*INCY)
          The vector y.

INCY

          INCY is INTEGER
          The increment between elements of Y. INCY > 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.
