midpoint_adaptive_test, a C code which calls midpoint_adaptive(), which solves one or more ordinary differential equations (ODE) using the (implicit) midpoint method, relying on fsolve() to solve the implicit equation, and using an adaptive timestep. Plots of the solution and timestep history are created using gnuplot().
