i don't know why i obtain the error:Not enough input arguments...Any help?
Thank you very much

Those function calls would be much simpler if you just put all of the parameters into a scalar structure and passed that. That number of positional input arguments makes it highly likely that you mave missed one or two, or got them in the wrong order.
In any case, please show us the exact error message. This means all of the red text.

yes of course, i have extrapolated that code from an implicit, simpler but bigger one.. i think that the error is related with the ode call but i am not sure about that

As the error states, you are not calling the function nozzlesinglebobbgola with enough input arguments:
nozzlesinglebobbgola(x, Ynozzle, xstartconica,xfineconica,Ralfa_end,Rbeta_end,alfa_end_rad,beta_end_rad,xc_end,yc_end,Lnozzle_end,raggio_end,f2) % how you call it
nozzlesinglebobbgola(x, Ynozzle, xstartconica,xfineconica,Ralfa_end,Rbeta_end,alfa_end_rad,beta_end_rad,xc_end,yc_end,Lnozzle_end,raggio_end,f3,f2,f1) % how you defined it
Or with the intermediate variables removed for clarity:
nozzlesinglebobbgola(x, Ynozzle, .. ,raggio_end,f2) % how you call it
nozzlesinglebobbgola(x, Ynozzle, .. ,raggio_end,f3,f2,f1) % how you defined it
Using so many positional input arguments is buggy (e.g. like this question) and makes the code very difficult to understand. Avoid doing this. I strongly recommend that you do either of these:
  1. put all of those parameters into one scalar structure and pass that.
  2. use a nested function, then you don't need those input arguments at all (nor the anonymous function).
