Ongun Palaoglu:
i can be a matrix, though we don't advise using i since it's also sqrt
(-1) and that opens up the possibility of problems.  Excuse me for not
seeing where you defined i, but I looked again in your
playbutton_callback() and I still don't see where it is defined.  If
you put a breakpoint there, does it give any values?  Are they foating
point or integer or logical?  If you do see values in the debugger,
then perhaps you just snipped out some of your code before you posted
it.

And #2 is "still" not a question.
