=================================== pst-ode PSTricks package https://gitlab.com/agrahn/pst-ode =================================== Alexander Grahn, (c) 2012--today `pst-ode' 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>}{t_0}{t_e}{N}{x⃗_0}{f⃗(t,x⃗)} The state vectors x⃗ found at N equally spaced output points between t_0 and t_e 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 x⃗ and the integration parameter t. The initial condition vector x⃗_0 and the right-hand side f⃗(t,x⃗) 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').
