Fit of own function in plot

Dear community I am stuck with a task to do. I have a dataset where I can plot figures out of it. Next step for me is to fit a Cole Cole function and obtain the parameters from it. I have seen normal linear fit or nonlinear fit from examples but I can't succeed in plotting the Cole Cole function into my plots. Can someone please help me with it?

I have put everything that is needed in the attachments.

Thank you in advance

Where is the rest of the code? All your code does is read it in and plot it. Where is your call to nlmfit()????

I don't have it. I tried to fit with the app that was within the MatLab program

The documentation in fit() function is good. Just follow the guidance on fit a curve defined by a file.
