ARGUMENTS

26       N       (input) INTEGER
27               The number of elements in the vectors CX and CY.
28
29       CX      (input/output) COMPLEX*16 array, dimension (N)
30               On  input, the vector X.  On output, CX is overwritten with C*X
31               + S*Y.
32
33       INCX    (input) INTEGER
34               The increment between successive values of CY.  INCX <> 0.
35
36       CY      (input/output) COMPLEX*16 array, dimension (N)
37               On input, the vector Y.  On  output,  CY  is  overwritten  with
38               -CONJG(S)*X + C*Y.
39
40       INCY    (input) INTEGER
41               The increment between successive values of CY.  INCX <> 0.
42
43       C       (input) DOUBLE PRECISION
44               S        (input)  COMPLEX*16  C  and  S  define a rotation [  C
45               S  ] [ -conjg(S)   C  ] where C*C + S*CONJG(S) = 1.0.
