Not terribly useful. This is an example, not a fitting function and it is not very well written. It is, however, slightly more useful than the poor documentation on the function nlinfit.

The code does not seem to be performing a fit to a Lorentzian, though, as the function fun.m (why not give it a more useful name?) is multiplied by 2 for some reason and the (x-x_0) term in the denominator is multiplied by 4 for some reason. Possibly this is a standard form in some field I have never come across, but this is certainly not the Lorentzian function I am interested in fitting. It is easy enough to fix, but worth pointing out to others who might use this.
