This package defines `\pstODEsolve` for solving initial value problems for sets of Ordinary Differential Equations (ODE) using the Runge-Kutta-Fehlberg (`RKF45`) method with automatic step size adjustment.

`\pstODEsolve[<options>]{<result>}{<output format>}{`t0`}{`te`}{`N`}{`x0`}{`f`(`t`,`x`)}`

The state vectors x found at N equally spaced output points between t0 and te are stored in the PostScript object `<result>`, formatted according to the second argument `<output format>`, as a long list of values. `<output format>` lists the quantities to be stored in `<result>`. The user can select from the elements of x and the integration parameter t.

The initial condition vector x0 and the right-hand side f`(`t`,`x`)` of the ODE system can be input in algebraic notation, if desired. RPN (Postfix) notation of PostScript can as well be used.

`<result>` can be directly used as the `<data>` argument of `\listplot{<data>}` (package `pst-plot`) or `\listplotThreeD{<data>}` (package `pst-3dplot`).
