If you can, would you explain why choosing coupling with negative RGA elements will introduce instability ? In MIMO u and y are vectors so would it not mean that with a negative coupling, it would just affect the coupling in the opposite direction. (sorry if my question is weird, still a little new to this).

Thank you so much! It helped me a lot :)
