**pendulum_ode**,
a MATLAB code which
sets up and solves a system of
ordinary differential equations (ODE) that represent the behavior
of a linear pendulum of length L under a gravitational force of strength G.

The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.

**pendulum_ode** is available in
a MATLAB version and
an Octave version and
a Python version.

matlab_ode, MATLAB codes which set up various ordinary differential equations (ODE).

- pendulum_conserved.m, evaluates a quantity that should be conserved for the ODE.
- pendulum_deriv.m, returns the right hand side of the ODE.
- pendulum_exact.m, returns the exact solution of the ODE.
- pendulum_parameters.m, returns parameters for the ODE.
- pendulum_period.m, returns the period of the ODE.
