Creating Product Automata Matrix (Let X). Given the two input matrixes M and N

Let M =[0 1;1 0], N=[0 1;0 1], Here, M is Finite state Machine-1 (FSM-1), N is FSM-2. There is no level transition(such as: a,b,c etc.). It's easy to calculate prodcut automata by manually and also by commend: kron (M,N) [kron for kroneker Product].

Ans: Product Automata matix is [0 0 0 1; 0 0 0 1; 0 1 0 0; 0 1 0 0]

But, If there is level transition (a,b,c etc.) Kroncer Product will not work, then what I have to do? Such as: M = [0 1; 1 0], N= [0 1, 0 b]. How, I can calculate the product automata matix from this given matirx. There can be multiple level transition (such as: a,b,c etc).

Manual answer: Product Automata matix is: [0 0 0 1; 0 0 0 b; 0 1 0 0; 0 b 0 0].
