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:

    I was put into jail as I was going to the shoemaker’s to get a shoe which was mended. When I was let out the next morning, I proceeded to finish my errand, and, having put on my mended shoe, joined a huckleberry party, who were impatient to put themselves under my conduct; and in half an hour ... was in the midst of a huckleberry field, on one of our highest hills, two miles off, and then the State was nowhere to be seen.
    Henry David Thoreau (1817–1862)

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