Hi, I have problems with fitting with Mathematica. I use the "NonLinearFit", and I define a equation. I have a table of data points that I would like to fit with my function. Since now, there is no Problem. But, when I give the initialised parameters, because of the big number of parameters, Mathematica has Problem to find a good fit. That's why I would like to give restriction of the parameters. But since now, I haven't find a possibilty to give restrictions, either before the Nonlinearregress, or in the Nonlinearregress. When somebody have seen the same problem, it can be help me. Thanks, Ravi
