NAME
       clargv.f -

SYNOPSIS
   Functions/Subroutines
       subroutine clargv (N, X, INCX, Y, INCY, C, INCC)
	   CLARGV generates a vector of plane rotations with real cosines and complex sines.

Function/Subroutine Documentation
   subroutine clargv (integerN, complex, dimension( * )X, integerINCX, complex, dimension( * )Y, integerINCY, real, dimension( * )C, integerINCC)
       CLARGV generates a vector of plane rotations with real cosines and complex sines.

       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) ) = ( r(i) )
	       ( -conjg(s(i))  c(i) ) ( y(i) ) = (   0	)

	       where c(i)**2 + ABS(s(i))**2 = 1

	    The following conventions are used (these are the same as in CLARTG,
	    but differ from the BLAS1 routine CROTG):
	       If y(i)=0, then c(i)=1 and s(i)=0.
	       If x(i)=0, then c(i)=0 and s(i) is chosen so that r(i) is real.

       Parameters:
	   N

		     N is INTEGER
		     The number of plane rotations to be generated.

	   X

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

	   INCX

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

	   Y

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

	   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.

	   INCC

		     INCC is INTEGER
		     The increment between elements of C. INCC > 0.
