Octave users,

        Recently I've developed a suite of 6 explicit Runge-Kutta ode
integrators.  They are similar in functionality to octave's built-in
lsode() function.  There are 3 fixed-step integrators and 3
variable-step integrators.  All (explicit RK) integrators are
single-step methods. 

- ode23.m : variable step, 2nd-3rd order, Runge-Kutta, single-step
- ode45.m : variable step, 4th-5th order, Runge-Kutta, single-step
- ode78.m : variable step, 7th-8th order, Runge-Kutta, single-step

- rk2fixed.m : fixed step, 2nd order, Runge-Kutta, single-step method
- rk4fixed.m : fixed step, 4th order, Runge-Kutta, single-step method
- rk8fixed.m : fixed step, 8th order, Runge-Kutta, single-step method

- pendulum.m : a sample m-file script that runs all solvers
- penddot.m  : derivative function file, returning dy/dt for a simple
