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 variable and/or state:

    There is not so variable a thing in nature as a lady’s head-dress.
    Joseph Addison (1672–1719)

    Feign then what’s by a decent tact believed
    And act that state is only so conceived,
    And build an edifice of form
    For house where phantoms may keep warm.
    William Empson (1906–1984)
