I am using MATLAB 7.0.1 (R14SP1) over a network. In addition to the network copy of MATLAB, there is also a local copy of MATLAB installed on each of the computers within that network.
In MATLAB, I select "File -> Preferences…" from the menu bar to change the preferences. For example, in the "Preferences" window, I select "General -> MAT-Files" and then check the "Ensure backward compatibility (-v6)" check box.
I find that after closing and restarting MATLAB, subsequent MAT-files that I generate are not backward compatible, even though the "Ensure backward compatibility (-v6)" check box remains checked.
