A **Noncommutative Signal-Flow Graph** (NSFG) is a mathematical representation used in control theory and systems engineering to describe complex systems where the variables may not commute. In conventional systems, the variables involved in signal-flow graphs typically commute, meaning that the order of multiplication does not affect the result (i.e., \\(AB = BA\\)).
