Curve Fitting to high order exponential function

Hello everybody, this is my first question here.
What I was trying to do is to fit an exponential function to a data. I already tried Matlab's Curve Fitting Tool, however it only fits exponential functions up to 2nd order. My data is more complex than that unfortunately, therefore 2nd order fit doesn't give me good result. Do you know any other tools or methods that I can use in Matlab to make the exponential fitting higher than 2nd order ?
Thanks in advance
Anil

Hi Alan,
Have you tried using the System Identification APP in MATLAB. It the App can be used for identifying linear models given data which I think you want to achieve. Documentation for the app can be found at the following link:
There are other functions like 'iddata' and 'ssest' where given data and order we can obtain a state space model for the plant. Kindly refer to the following link:
Hope this helps.
