Right now i have some functions that are in different matlab file but my app designer uses them because they are in the same folder. I copied them into the tap of code browser "functions" and i can see them on my screen. Is it possible to use my functions in app designer without additional files with those function? if yes how do i call up? I uploaded code with my functions in the function code browser

         %Funkcja do obliczania azymutu w radianach
function arctan = arctan(app, licznik, mianownik )
if true
  % code
wartość arctg z wartoścli bezwzględnej licznik/mianownik
arctg = atan(abs(licznik/mianownik));
if licznik == 0 
  arctan = 0;
else
  if licznik>0 && mianownik>0
      arctan = arctg;
  else
     if licznik>0 && mianownik<0
         arctan = pi - arctg;
     else
         if licznik<0 && mianownik<0
             arctan = pi + arctg;
         else
             arctan = 2*pi - arctg;
         end
     end
  end
end
end
end
And here it is how i use it:
    AW1W2 = arctan(dyW1W2,dxW1W2);
AW2W3 = arctan(dyW2W3,dxW2W3);
  end

If I understand your question correctly, you want to have all your code in the app, without the need for separate files? Yes this is possible in app designer. From the code you pasted, the only thing you are missing is when you call your function, include app as the first argument, like this:

AW1W2 = arctan( app, dyW1W2,dxW1W2);
