I'm new to Mathematica 4.0, so I apologize if this question is overly trivial (and please let me know if there's a place for trivial question). I have a list that I'd like to fit to the function: A + B*Sin[C*x+D] In other words, I'd like to find the (approximate numeric) values of A,B,C,D that yield the best fit to my data. I tried using Fit[], but it only applies to linear combinations of functions, and couldn't optomize the values of C and D. For this specific problem, I'm guessing some sort of Fourier transform might work, but I'm interested in a more general solution -- for example if Sin[] were replaced with a more complicated function. Any help appreciated! Sent via Deja.com http://www.deja.com/ Before you buy.
