I am new to GSL and new to nonlinear fit as well. I would like to use the nonlinear fit of GSL, could you please help?
You should familiarize yourself with the basics of non-linear regression / non-linear least squares first. You should be able to use the GSL example as a starting point. Please post your code to the list so that people can see what might be wrong.
To get initial values, you can try different values of a, b and c and see what f(x) values they give you. Try different values until you get something that resembles your f(x) data. Then use them as the initial values.
