The fcn function set with SetFCN doesn't take variables as paramaeter, but instead it read those values from global memory. Example: delta = (z[i]-func(x[i],y[i],p[i],par))/errorz[i]; here z[i], x[i], y[i] atc are GLOBAL and I cannot pass them to fcn. ( PS : SetFCN is overloaded with: (*) (fcn(fixed number of parameters)) Maybe one can use the (*) version to create his own fcn ? ) Mauri On Fri, 13 Jul 2001, Rene Brun wrote: > Hi Maurizio, > > Could you clarify your point?
