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.
