stetter_ode, a Python code which sets up and solves an ordinary differential equation (ODE) for which a specific time step sequence causes the implicit trapezoidal method to be unstable, while the implicit midpoint method will be stable. The right hand side function f(t,y) is periodic, discontinuous, and piecewise linear.
