On which version of Mathematica are you working. If you're on 6 or 7
did you read at least this documentation:
http://reference.wolfram.com/mathematica/tutorial/CurveFitting.html.
Which part of it you didn't understand?

At the end of the calculation I get a list with theoretical x and y values. Now, since the calculation is made by using some parameters, I would like Mathematica to find the best set of fitting parameter that fit the experimental data.
