This is relatively simple: When a user pushes a button in App Designer, I want them to see a message saying that the operation is execuing because it takes a few minutes to complete. In the example below, the "Working..." message is not displayed prior executing the loop, thus the user only sees "Done" when the operation is over. I suspect that I need the function to display the "Working" text and then call the other, time consuming function, but it is not clear how I do this inside App Designer. Thanks.

function buttonpush(app,event)
app.myEditField.Value= 'Working...'
for i =1:100
    x[i]=stuff
end
app.myEditField.Value = 'Done'
end

One way is to pause a bit (for exapmle, 0.01 second) in order to display the text before doing long-time operation.

function buttonpush(app,event)
    app.myEditField.Value= 'Working...';
    pause(0.01)
    for i =1:100
        x[i]=stuff
    end
    app.myEditField.Value = 'Done';
end

Or, you can use progress message dialog (uiprogressdlg).

function buttonpush(app,event)
    d = uiprogressdlg(app.UIFigure,'Title','Progress', 'Indeterminate','on');
    d.Message = 'Working...';
    for i =1:100
        x[i]=stuff
    end
    d.Message = 'Done';
    close(d)
end
