Using appdesigner I have developed a GUI that runs pretty good. I now want to take some variables that are defined in the app code and use them in a script I am developing. How do I do this? This is a function that is in the app designer and I want to use "NewInterval" in my script.

methods (Access = public)

function WhatIntervalSelected (app, ~)

if app.Interval1Button.Value == true;

NewInterval =1;

elseif app.Interval2Button.Value == true

NewInterval =2 ;

elseif app.Interval3Button.Value == true;

NewInterval =3;

elseif app.Interval4Button.Value == true

NewInterval =4;

elseif app.Interval5Button.Value == true

NewInterval =5;

else

NewInterval = 6;

end

How do I get NewInterval into my MATLAB Script?

在 MATLAB Online 中打开

You have few options, depending on the complexity of your app, I could suggest you to get the app instance in your script.

Set a Tag, or a unique name for your app in Component Browser, under UIFigure - Identifiers, and get its handle this way:

%  in script
app = get(findall(0, 'Tag', 'AppUIFigure'), 'RunningAppInstance');
%                            ^^^^^^^^^^^

Set your NewInterval as a property, and just call it within your script as

app.NewInterval

You can also convert your script to function that you pass the NewInterval property (must define it that way too), but this is a bit of a hassle and not necessary.
