bdf2, a C++ code which solves one or more ordinary differential equations (ODE) using the (implicit) backward difference formula order 2 (BDF2), with a version of fsolve() handling the associated nonlinear equation, and using a fixed time step.

bdf2 is available in a C version and a C++ version and a Fortran77 version and a Fortran90 version and a MATLAB version and an Octave version and a Python version.
cpp_ode_solver, a C++ code which solves one or more differential equations (ODE) using a method of a particular order, either explicit or implicit. Some methods require a nonlinear equation solver. Some methods used a fixed stepsize, while others adapt the stepsize based on an error estimate.
