`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.
