Running the code, getting the old results... Indeed, forgot to save one of the edited .m files, again. What's the keyboard shortcut to save ALL open .m files at once?
You can add a shortcut for the Save All action (at least in R2015a which I am using).
I chose CTRL+ALT+S:
How you get there is described in the MATLAB documentation:
On the Home tab, in the Environment section, click Preferences. Select MATLAB > Keyboard > Shortcuts.
