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:
“George Shears ... was hanged in a barn near the store. The rope was thrown over a beam, and he was asked to walk up a ladder to save the trouble of preparing a drop for him. “Gentlemen,” he said, “I am not used to this business. Shall I jump off or slide off?” He was told to jump.”

“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,”
