I don't have it installed, but if you give me the error messages I'm gonna take a look.

@@azzagamal9243 Thanks! Had to install Matlab after all to figure this out, but now it should work (or at least on version R2018a it does).
Problems were 1) the octave commands "endif", "endfor", "endfunction" which I didn't know that Matlab required to all be just "end", 2) the unequal operator "!=" had to be "~=". Octave makes so much more sense btw 🤦‍♂

​@@Makstuff thank you very much

This was actually a good explanation. Thank you for the video.
