I'm implementing a digital delay using real-time audio plugins. I need a button on the GUI that does the same of this code. Basically I want to give the delay time as an average time between 4 inputs, using a dedicated button on the GUI to avoid knowing the exact value of such time in milliseconds. I'm sure I cannot just use this code, is there an "optimal way" to do it?

a = zeros(1,4);
disp('Press now to start the sequence')
pause
tic
%requesting input
disp('Press')
pause
a(1) = toc;
tic
%requesting input
disp('Press')
pause
a(2) = toc;
tic
%requesting input
disp('Press')
pause
a(3) = toc;
tic
%requesting input
disp('Press')
pause
a(4) = toc;
%average
time = mean(a);

AverageTimerUI.mlapp

If you are trying to create a UI, you could create an app with App Designer as shown attached. Let me know if this addresses your question.

I'm forced to use the UI designer with object oriented languages, this one:

properties (Constant)
        PluginInterface = audioPluginInterface(...
            audioPluginParameter('DoubleEcho', ...
            'Style','vtoggle', ... 
            'Layout',[2,6], ... 
            'DisplayNameLocation','Above'),...

            'DisplayName','Echo Level', ...
            'Mapping', {'lin',0,3}, ...
            'Style', 'rotaryknob', ...
