How to link between Mathemetica and Matlab

I am working in matlab with the image processing toolbox. I need to fit a data, and since I do not have the curve fitting toolbox, I will use Mathematica for this task. However I do not know how the two softwares communicate. In other words how Mathematica receives the raw data from MATLAB and how does it send the fitted curve to MATLAB

Assistance will be appreciated.

Thanks

Source code is included.

Said, you have access to a LOT OF Curve Fitting Toolbox licenses at your university. Just in case you like to stay within MATLAB...

Thanks Walter, I am really comfortable with MATLAB and I will try to compute the derivative of a curve based on discrete points before going to mathematica.
