I have a table of xy data which needs to be modelled using a damped sine wave. What Windows program (preferably free or trial) can do that for me?

There are over 600 data points per model.

Thanks!

    If you're going to fit a "damped" wave (what is your definition of a damped wave, anyway?) to your points, know that fitting oscillatory functions can be a difficult problem. You might want to post a scatter plot of your points here...2011-04-30
