{wiki=Routh–Hurwitz_theorem}
The Routh–Hurwitz theorem is a mathematical criterion used in control theory and stability analysis of linear time-invariant (LTI) systems. It provides a systematic way to determine whether all roots of a given polynomial have negative real parts, which indicates that the system is stable.
