ode solvers v1.07

[Marc Compere]

Octave users,

        The latest and greatest versions of 6 Ordinary Differential Equation
(ODE) solvers have been posted to the octave-sources mailing list.  This
is Copyrighted & licensed software (GPL) designed for use with Octave. 
They are also available and being maintained at
http://marc.me.utexas.edu/tmp/octave_ode_solvers/ode_v1.07/.

        The archive octave_ode_solvers_v1.07.tar.gz contains 6 single-step
Runge-Kutta ODE solvers along with 2 files demonstrating example uses of
each solver:

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

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

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

        None of these solvers are designed to work with stiff systems, however,
the fortran code sdirk4.f is a stiff ODE solver written by E. Hairer and
arranged for use within Octave by Marc Compere.  More infomation is
available at
http://www.che.wisc.edu/octave/mailing-lists/help-octave/2000/264.

Best regards,
Marc Compere
