Thanks you all for your replies.
Indeed, what you suggested only solves my partially my issue. I guess I
should get deeped into the problem...
Each xi I wrote in the previous messages represents of couple of (x,y)
coordinates in the form {{a1,y1},{a2,y2}} which represents the points to
which I have to apply function Fit[].
I.e. xx={{x11,x12,x13},x2,x3,x4,{x51,x52},x6,{x71,x72},x8}=
{...,{{a61,y61},{a62,y62}},...}
Now, if I set Fit[] to Listable, then I would get
Fit[xx,{1,x},x]={...,{{Fit[a61,{1,x},x],Fit[y61,{1,x},x]},{Fit[a62,{1,x},x],
Fit[y62,{1,x},x]}},...}
which obviously something meaningless.
I would therefore need something that "flattens" xx down to a list so that
only tokens like {{a1,y1},{a2,y2}} appear. I would then apply Fit[] in the
correct way, and then I would like to construct a list with the same pattern
that xx had...
Is it confusing? It is to me...
Please, let me know if you need further explanations. Thanks you all for
your help!
