lorenz_ode, a C++ code which approximates solutions to the Lorenz system, creating output files that can be displayed by gnuplot.
midpoint_explicit, a C++ code which solves one or more ordinary differential equations (ODE) using the (explicit) midpoint method.
midpoint_fixed, a C++ code which solves one or more ordinary differential equations (ODE) using the (implicit) midpoint method, using a fixed point method for the implicit equation.
