ARGUMENTS

22       N       (input) INTEGER
23               The number of elements in the vectors CX and CY.
24
25       CX      (input/output) COMPLEX array, dimension (N)
26               On input, the vector x.  On output, CX is overwritten with  c*x
27               + s*y.
28
29       INCX    (input) INTEGER
30               The increment between successive values of CX.  INCX <> 0.
31
32       CY      (input/output) COMPLEX array, dimension (N)
33               On input, the vector y.  On output, CY is overwritten with -s*x
34               + c*y.
35
36       INCY    (input) INTEGER
37               The increment between successive values of CY.  INCY <> 0.
38
39       C       (input) COMPLEX
40               S       (input) COMPLEX C and S define the matrix [  C   S   ].
41               [ -S   C  ]
