end
end
% App creation and deletion
methods (Access = public)
% Construct app
function app = tutorialApp
% Create UIFigure and components
createComponents(app)
% Register the app with App Designer
registerApp(app, app.UIFigure)
if nargout == 0
clear app
end
end
% Code that executes before app deletion
function delete(app)
% Delete UIFigure when app is deleted
delete(app.UIFigure)
end
end
end
Every time I select a button it should display that number in a textarea.

Do you need individual buttons for each digit, or would a uispinner or uidropdown that allows you to select a number between 0 and 9 be sufficient?

If you need buttons only, have a property as follows
properties (Access = private)
Number % Description
end
Then just have callbacks to all your buttons so that OnClick Number gets assigned the button value.
Then just set your text box value to Number
app.TextArea.Value = Number;
or you could directly set app.TextArea.Value to number in the callbacks
