How to set "TightInset" globally?

I'm trying to set up a MATLAB script that needs to print multiple figures. I want to set up the settings globally so that I don't have to paste the code each time. How do I set up "TightInset" globally so that I don't have to paste it each time. At the moment I have been using:

set(gca,'LooseInset', max(get(gca,'TightInset'), 0.02))

But want this to be set globally similar to

set(0, 'defaultFigureUnits', 'inches', 'defaultFigurePosition', [0 0 3.5 3]);

You cannot control TightInset: it is read-only.

You can set a default LooseInset though.

set(groot, 'defaultAxesLooseInset', [0.04 0.05 0.02 0.02])

Thanks very much! What's the difference between using

set(groot,...)

and

set(0,...)

???

Thanks!
