State Variable

A state variable is one of the set of variables that are used to describe the mathematical "state" of a dynamical system. Intuitively, the state of a system describes enough about the system to determine its future behaviour. Models that consist of coupled first-order differential equations are said to be in state-variable form.

Famous quotes containing the words state and/or variable:

    The almost unexplored Everglades lay close by and with a half- hour’s start a man who knew the country was safe from pursuit. As one man cheerfully confided ..., ‘A boat don’t leave no trail, stranger.’

    Walked forth to ease my pain
    Along the shore of silver streaming Thames,
    Whose rutty bank, the which his river hems,
    Was painted all with variable flowers,
