It is of course possible to change the command window's text size by setting preferences, using the GUI. Is there a way to do the same programmatically by executing a MATLAB command or script? That would be much more convenient (I am calling MATLAB through engOpen() from C). At the moment MATLAB is using a 6-pixel font on my hi-dpi monitor (3840x2160), which is really inconvenient. The console has a menu bar, but it offers none of the functionality a normal OS cmd window has.

在 MATLAB Online 中打开

s = settings;
s.matlab.fonts.codefont.Size.PersonalValue = 16;

@marcel hendrix, it seems to work fine. Here's the difference you can notice if the change in fontsize settings is done from 10 to 16

Of course that works. That is the GUI command window.

This is what I see after engOpen.

What I need could be in there, but I can't find it. Voss's answer concurs with the documentation but does nothing. I assume the setting is changed, but the engOpen command window has no handler / message loop for changed settings. What might be needed is a function that explicitly forces the engOpen console window to reinitialize or update its settings. I tried restarting MATLAB: it did not work, still a tiny font.
