euler, a C code which solves one or more ordinary differential equations (ODE) using the forward Euler method.
midpoint_fixed, a C code which solves one or more ordinary differential equations (ODE) using the (implicit) midpoint method, using a fixed point iteration for the implicit equation.
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.
rk4, a C code which applies the fourth order Runge-Kutta (RK) algorithm to estimate the solution of an ordinary differential equation (ODE).
