The pst-ode PSTricks package
https://gitlab.com/agrahn/pst-ode
© 2012–\today Alexander Grahn
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).

pst-ode – Solving initial value problems for sets of Ordinary Differential Equations
The 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.
The result is stored as a PostScript object and may be plotted later using macros from other PSTricks packages, such as \listplot (pst-plot) and \listplotThreeD (pst-3dplot), or may be further processed by user-defined PostScript procedures. Optionally, the computed state vectors can be written as a table to a text file.
