Re: nonlinear differential equations

[Marc Compere]

Reinhold,

        Hi, I recently saw your posting at the Octave archive, 
http://www.octave.org/mailing-lists/help-octave/2001/683.  Have you gotten 
your equations solved?  I've written several ODE solvers for octave that are 
free for your use & perusal.  I've also included an example that shows the 
nitty gritty in simulating a simple pendulum (i.e. solving ODE).  The solvers 
as well as the example can be found at:

        http://marc.me.utexas.edu/tmp/octave_ode_solvers/ode_v1.12/

        You need to write a driver m-file (which will call ode45 or lsode to 
solve 
your equations) and an equation m-file (that defines your equations).  The 
example driver in the directory above is called pendulum.m and the equations 
are defined in a file called penddot.m.  Hope this helps.

Regards,
Marc
