I am trying to fit a Lorentzian Curve of sorts to some data. However, I can't seen to get the curve to fit my data even though I have what I know to be about the right numbers. The fitted curve is so far off that I am assuming that did something majorly wrong. I left, in two arrays, some real data to which I want to fit the curve. Also, my guesses should be pretty close (a1=3, a2=.1, a3=2.6).
So if anyone can help me out or point me in the right direction that would be greatly appreciated.
Thanks
