PURPOSE
       zdrot  Apply a plane rotation, where the cos and sin (c and s) are real
       and the vectors x and y are complex.


ARGUMENTS
       N (input)
                 On entry, N specifies the number of elements in the   vector.
                 N must be at least one for the subroutine to have any visible
                 effect.  Unchanged on exit.


       X (input/output), dimension (1+(N-1)*abs(INCX))
                 On  entry,  the incremented  array X must contain the  vector
                 x. On exit, X is overwritten by the updated vector x.


       INCX (input)
                 On  entry,  INCX specifies  the  increment  for  the elements
                 of  X. INCX must not be zero.  Unchanged on exit.


       Y (input/output), dimension (1+(N-1)*abs(INCY))
                 On  entry,  the incremented  array Y must contain the  vector
                 y. On exit, Y is overwritten by the updated vector y.


       INCY (input)
                 On  entry,  INCY specifies  the  increment  for  the elements
                 of  Y. INCY must not be zero.  Unchanged on exit.


       C (input)
                 On entry, the cosine.  Unchanged on exit.


       S (input)
                 On entry, the sin.  Unchanged on exit.
