I do not have any intuition into that... seems that Dr Yaser is saying that you have to look at the complex parameter as a 2D vector of real numbers and compute derivative wrt that vector.. this why the # of parameters doubles. is this an "engineering" solution?? or is it really mathematically correct.. there seems to be much more to this than meets the eye..

Don't worry, it's just as simple as it appears. For this purpose, a complex parameter
is simply two real parameters, since there is no multiplication by complex numbers involved.
