NAME
     clartv - apply 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( * )



     #include <sunperf.h>

     void clartv(int n, complex *cx, int incx, complex  *cy,  int
               incy, float *sc, complex *s, int incc) ;

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.

     Y         (input/output)  COMPLEX  array,  dimension  (1+(N-
               1)*INCY)
               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.
