**midpoint_gsl_test**,
a C code which
calls the Gnu Scientific Library (GSL) implicit midpoint method
solver for ordinary differential equation (ODE), and uses
gnuplot() to plot the resulting solution.

euler, a C code which solves one or more ordinary differential equations (ODE) using the forward Euler method.

lorenz_ode, a C code which sets up the Lorenz system of ordinary differential equations (ODE), which exhibit sensitive dependence on the initial conditions.

midpoint_explicit, a C code which solves one or more ordinary differential equations (ODE) using the (explicit) midpoint method, also called the modified Euler method.

midpoint_fixed, a C code which solves one or more ordinary differential equations (ODE) using the (implicit) midpoint method, applying a fixed point iteration to solve the associated nonlinear equation.

ode, a C code which solves a system of ordinary differential equations (ODE), by Shampine and Gordon.

ode_moshier, a C code which implements the Adams-Bashforth-Moulton and Runge-Kutta (RK) methods of solving systems of ordinary differential equations (ODE), by Steven Moshier.

predator_prey_ode, a C code which solves a pair of predator prey ordinary differential equations (ODE).
