If your edit fields have systematic names you can do it like this:
for i=1:3
app.(sprintf('EditField%d',i)).Value
end
You just need to pay attention, that you might need to rename the first EditField to EditField1.
You can also create EditFields in a loop, which is really helpful, when you need to create more than 2 or 3.
For example you could put this in your startupFcn:
for i=3:-1:1
editFields(i)=uieditfield(app.UIFigure,'numeric');
editFields(i).Position = [90 100+i*40 100 22];
end
app.editFields=editFields; %you need to add the editFields property to your app for this to work
Then you can simply loop through your handles:
for i=1:3
app.editFields(i).Value;
end
