You may pick out a model first to fit your data onto. There a wide variety of models available in Matlab and the choice would depend on the kind of data that you have - if you can post the data here along with your question, you may get better recommendations.
To start with, I would recommend polyfit or lsqnonlin. I might also try playing with simple Neural Network models as a next step.
Have a look at this doc as well:

Hope it helps!
