Double pendulum equations of motion

  1. Mar 2, 2013 #1
    Hi,

    I am trying to create displacement time series graphs of a double bar pendulum using Matlab.

    Am I correct in assuming that if I use the ode45 solver to integrate the equations below I can plot displacement time series graphs? Are these the correct coupled first order ODEs to use?
