说明：  求解简单微分方程。模拟双摆运动并附简单说明材料。(For animation, the program uses Matlab s normal plot command combined with the drawnow command. It is based on the ode45 solution of the corresponding differential equations. Comprehensive documentation is provided, including a sketch of the most important steps of how to derive the equations of motion. A simple Mathematica notebook contains all of the manipulations. )
