clargv(3F)

NAME
     CLARGV - generate a vector of complex plane rotations with real cosines,
     determined by elements of the complex vectors x and y

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

         INTEGER        INCC, INCX, INCY, N

         REAL           C( * )

         COMPLEX        X( * ), Y( * )

PURPOSE
     CLARGV generates a vector of complex plane rotations with real cosines,
     determined by elements of the complex vectors x and y.  For i = 1,2,...,n

        (        c(i)   s(i) ) ( x(i) ) = ( a(i) )
        ( -conjg(s(i))  c(i) ) ( y(i) ) = (   0  )


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

     X       (input/output) COMPLEX array, dimension (1+(N-1)*INCX)
             On entry, the vector x.  On exit, x(i) is overwritten by a(i),
             for i = 1,...,n.

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

     Y       (input/output) COMPLEX array, dimension (1+(N-1)*INCY)
             On entry, the vector y.  On exit, the sines of the plane
             rotations.

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

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

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