[Help-gsl] nonlinear fit

[Irina Stefan]

Hi,

This is probably a very easy question, but I'm not very comfortable with gsl, 
so here it goes.
I'm writing a routine to fit a Gaussian to a set of data points. I'm pretty 
much modifying the example from the gsl manual. However, I want to perform an 
unweighted fit and I'm not sure what function to use as f_i.

Cheers,
Rena
