rk2, a Python code which solves one or more ordinary differential equations (ODE) using a Runge-Kutta order 2 explicit method, also known as Heun's method, or the modified Euler method, or the explicit midpoint method.

rk2 is available in a C version and a C++ version and a Fortran90 version and a MATLAB version and an Octave version and a Python version.
python_ode_solver, a Python code which solves one or more differential equations (ODE) using a method of a particular order, either explicit or implicit. Some methods require a nonlinear equation solver. Some methods used a fixed stepsize, while others adapt the stepsize based on an error estimate.
