you will need to call the function save() in the pushbutton callback. The documentation for save() will give you a good explanation of how to do this.

when you put a break point before the save does handles.f exist?
if not when you create handles.f you will need to call guidata(hObject, handles); at the end of the function (before it goes back to the main gui section) to update the handles object.
or... possibly that maynot work... i just noticed that you're not using guide.
