[Help-gsl] about nonlinear fit of several functions simultaneously

Hi,all
I have datasets {f1, f2} over [X0,X1]. The task is to fit {f1,f2} 
simultaneously by assuming two function F1(a,b) and F2(a,b) where {a,b} are 
common parameters. How to realize this with the gsl Levenberg-Marquardt solver? 
I have used it for a single dataset (i.e., only {f} over [X0,X1]}. The solver 
seems to be designed for fitting only one function.
 
I have an idea that a piecewise function can be defined and thus fitted 
piecewisely. Is this right?
 
Does anyone have any idea for dealing with this?
Or can anyone recommend other library that can easily deal this situation?
thanks in advance
Liu
