clartv(3F)

NAME
     CLARTV - applie a vector of complex plane rotations with real cosines to
     elements of the complex vectors x and y

SYNOPSIS
     SUBROUTINE CLARTV( N, X, INCX, Y, INCY, C, S, INCC )

         INTEGER        INCC, INCX, INCY, N

         REAL           C( * )

         COMPLEX        S( * ), X( * ), Y( * )

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) )


ARGUMENTS
     N       (input) INTEGER
             The number of plane rotations to be applied.

     X       (input/output) COMPLEX array, dimension (1+(N-1)*INCX)
             The vector x.

     INCX    (input) INTEGER
             The increment between elements of X. INCX > 0.

             The vector y.

     INCY    (input) INTEGER
             The increment between elements of Y. INCY > 0.

     C       (input) REAL array, dimension (1+(N-1)*INCC)
             The cosines of the plane rotations.

     S       (input) COMPLEX array, dimension (1+(N-1)*INCC)
             The sines of the plane rotations.

     INCC    (input) INTEGER
             The increment between elements of C and S. INCC > 0.
