Question regarding function using radiobutton status

Lets say I have three radio buttons. If 1 is pressed, then variables x,y,z are certain values. If 2 is pressed, then variables x,y,z are different values, etc.

How would I write a function that outputs those variables and use it within the GUI code?

Greg - consider placing your three radio buttons in a button group panel and assigning a SelectionChangeFcn callback to this panel. Whenever the user selects a radio button, this callback will fire and you will be able to changes the variables as you see fit based on the selected radio button

 function uipanel1_SelectionChangeFcn(hObject, eventdata, handles)
 selectedRadioBtnStr = get(hObject,'String');
 if strcmpi(selectedRadioBtnStr, 'Radio Button 1')
    handles.x = 1;
    handles.y = 2;
    handles.z = 3;
 elseif strcmpi(selectedRadioBtnStr, 'Radio Button 2')
    handles.x = 11;
    handles.y = 21;
    handles.z = 31;
 elseif strcmpi(selectedRadioBtnStr, 'Radio Button 3')
    handles.x = 111;
    handles.y = 211;
    handles.z = 311;
 end
 guidata(hObject,handles);

We then save those changes to the handles structure using guidata. See the attached for an example.
