I have a reset button on my app, and 5 edit field (text) for various inputs. When pressing the reset button, it's supposed to clear the 5 text boxes to empty strings. I've tried other suggestions from other questions (like using 'set' and 'findobj') but none of them have worked. My professor said to create a string first, then set it to empty with our code, and test it with 'isempty' but he gave no further explanation.

set( findobj(gcf, 'type', 'uicontrol', 'style', 'text'), 'string', '')

app.edit1.Value = '';
app.edit2.Value = '';
app.edit3.Value = '';
app.edit4.Value = '';
app.edit5.Value = '';
if isempty(app.edit3.Value)
disp('Yes it is empty');
else
disp('No it is not empty');
end

Thank you! I thought I'd tried that before, but I guess I didn't do something right.
