ode_moshier, a C code which solves systems of ordinary differential equations. Two main methods are implemented, the Adams-Bashforth-Moulton integrator, and the Runge-Kutta integrator, by Steven Moshier.
ode_moshier is available in a C version.
midpoint_gsl_test, a C code which calls the Gnu Scientific Library (GSL) implicit midpoint method solver for ordinary differential equation (ODE), and uses gnuplot() to plot the resulting solution.
ODE, a C code which solves a system of ordinary differential equations (ODE), by Shampine and Gordon.
rk4, a C code which applies the fourth order Runge-Kutta algorithm to estimate the solution of an ordinary differential equation (ODE) at the next time step.
rkf45, a C code which implements the Watt and Shampine RKF45 solver for ordinary differential equations (ODE).
