-* Purpose
-* =======
-*
-* ZLARGV 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 ZLARTG,
-* but differ from the BLAS1 routine ZROTG):
-* 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.
-*
-* Arguments
-* =========
-*
-* N (input) INTEGER
-* The number of plane rotations to be generated.
-*
-* X (input/output) COMPLEX*16 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 (input) INTEGER
-* The increment between elements of X. INCX > 0.
-*
-* Y (input/output) COMPLEX*16 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) DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
