Fitting Complex data to complex model

Dear Everybody, I have a set of the nonlinear complex numbers and want to fit it to the complex model. The point is that the model parameters are real and same for the real and imaginary part of the model. There is clue in : http://www.mathworks.com/help/optim/ug/fit-model-to-complex-data.html but unfortunately it gave me complex numbers for my parameters instead of the real ones. Is there any solution that you could give me? Thank you in advance for your attention

If you want to ensure that your results are real, then reformulate your problem to be real. Express all complex numbers z by x + iy, wbere x and y are real.

Perhaps I did not express myself well. If you have some model parameters p that are "...real and same for the real and imaginary part of the model", then make those parameters p real, with no complex part. Put in complex numbers z = x + iy wherever you need to, and optimize over p.
