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. > Anybody knows how to do this kind of thing!? > The loop that I use for the calculation is itself a Module but I don't know if I can use this together with the Fit function... > > Any idea??? > > Many thanks. -R
