stiff_ode, a C++ code which considers an ordinary differential equation (ODE) which is an example of stiffness.
stiff_ode is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and an Octave version and a Python version.
lorenz_ode, a C++ code which approximates solutions to the Lorenz system, creating output files that can be displayed by gnuplot.
midpoint, a C++ code which solves one or more ordinary differential equations (ODE) using the (implicit) midpoint method.
predator_prey_ode, a C++ code which solves a pair of predator prey ordinary differential equations (ODE).
spring_ode, a C++ code which shows how line printer graphics can be used to make a crude illustration of a solution of the ordinary differential equation (ODE) that describes the motion of a weight attached to a spring.
