midpoint, a Python code which solves one or more ordinary differential equations (ODE) using the (implicit) midpoint method.
Unless the right hand side of the ODE is linear in the dependent variable, each midpoint step requires the solution of an implicit nonlinear equation. This code uses the nonlinear equation solver fsolve().
