How do I programmatically switch to Dark Mode (Dark Theme) in R2025a?

I am running R2025a pre-release. What are the commands to switch to dark mode?

This is supported from R2025a onwards. This is what you need to do

>> s = settings;
>> s.matlab.appearance.MATLABTheme.PersonalValue = "Dark";

theme('dark') % light | auto
% Or
theme(fig,'dark')
% Or
fig = figure(Theme='dark')
% or
fig.Theme = 'dark';
