WebJun 4, 2024 · If all you have is the function definition file (i.e. gcd.m ), when you hit "Save and run", Octave will itself call your function, but it's not clever enough and won't use any parameters in doing so. That's why you get an "undefined variable" error. That would be similar to you having only test = gcd () in your test file.
