bdf3, a Fortran90 code which solves one or more ordinary differential equations (ODE) using the (implicit) backward difference formula order 3 (bdf3), with a version of fsolve() handling the associated nonlinear equation, and using a fixed time step.

bdf3 is available in a Fortran90 version and a MATLAB version and an Octave version and a Python version.
f90_ode_solver, a Fortran90 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.
