# The `ode` Program

The GNU `ode` utility can produce a numerical solution to the initial value problem for many systems of first-order ordinary differential equations (ODE's). `ode` can also be used to solve systems of higher-order ODE's, since a simple procedure converts an n'th-order equation into n first-order equations. The output of `ode` can easily be piped to `graph`, so that one or more solution curves may be plotted as they are generated.

Three distinct schemes for numerical solution are implemented: Runge--Kutta--Fehlberg (the default), Adams--Moulton, and Euler. The Runge--Kutta--Fehlberg and Adams--Moulton schemes are available with adaptive stepsize.
