function simpleApp
% Create a figure and a UI control
f = figure('Visible','off');
uicontrol('Style','text', 'String','Hello, MATLAB Online!', ...
'Position',[20 50 200 40]);
% Show the figure
f.Visible = 'on';
end
This snippet creates a basic app that displays a message box. Custom apps allow you to tailor your MATLAB experience according to your needs.
Performance Tips
Optimizing code for efficiency is crucial in MATLAB, especially when working with large datasets.
Optimizing Code for Efficiency
