% ============= YOUR CODE HERE ==============
% Instructions: Return the 5x5 identity matrix 
%               In octave, we return values by defining which variables

I am a mentor for Andrew Ng's Machine Learning course.

The recommended fix for this issue is to use the correct set of programming exercise scripts.

There are two sets:

• One for Octave (it's in the "Programming Assignment" page).
• The other is for MATLAB 2019b and later - like MATLAB Online. It has the fix required for this "parts = parts(conf)" issue. The MATLAB version of the programming exercise scripts is on the page in Week 2 with the MATLAB Online setup instructions.

***** Other benefits of using the right set of scripts *****

If you get the MATLAB version of the programming exercise scripts, you also get the ".mlx" helper script file, with the built-in instructions and fancy Notebooks-like interface. That is not provided with the Octave version of the scripts.

You also get all eight programming exercises in one swipe- with Octave, you have to repeat the download-and-extract business eight times during the course.

********

So, please use the right programming exercise scrips - and stop modifying the submit functions. Many students break things when trying that. It's a bad day for everyone.

Thank you.
