[Help-gsl] Nonlinear least-square-fitting parameter domain

[Ricardo Zapata]

Hi,

Is there any way to give the parameters' range to the solver for 
nonlinear square-fitting? I need my parameters to be > 0. I used 
GSL_EDOM in my functions (f and df), but this makes the program to abort 
instead of trying a new parameter value.

Thanks,

Ricardo
