Description

A double pendulum simulator (written in Python 3) which uses the Runge-Kutta (RK) method to solve the set of differential equations from either the Lagrangian formulation or from the Hamiltonian formulation for the double pendulum problem.

Required modules

The following modules are used:

• numpy
• pygame

You can install them with the following command:

Usage instructions

Run ./double-pendulum -h to get a list of simulation parameters which can be set.

Notes on stability
