Button group

Answer 1

That does not appear to be possible in R2014b or later. It appears to me that the first button added to a uibuttongroup automatically has its Value set to 1.

Your options are:

1. set() the Value of the first button to 0 after it is added to the uibuttongroup; or
2. create a junk button first and add it to the uibuttongroup, and then after the other buttons are added, delete the junk button.

That's now how they operate I don't think. What you should use instead is a popup menu, or a listbox.
