I take it that you have a list of x coordinates, generated from a function f2(t), and a list of y coordinates generated from a function f1(t). You then want to fit a model f to the data. What's your upshot of a model? Did I understand your problem correctly? Once you have a model you want to fit, you can use Mathematicas FindFit function, which takes the option Method -> "LevenbergMarquardt". Sigmund
