Kepler. Given the large number of equations I need to solve, I think
using the standard 'expression / integrator' method may become too
messy, so I was looking into using the Differential System actor to keep
things tidy. The problem is I'm not sure how to correctly use the
actor. I found the documentation to be confusing and could not find any
tutorials for Kepler/Ptolemy II/Simulink to clarify. If someone could
write a quick tutorial using a minimal example (maybe an undamped
pendulum) or point me in the right direction, I would greatly appreciate
it! <br><br>Aside: The ODE's are in reduced (1st order) form, so it is really just a matter of getting it into Kepler.<br><br><br>Cheers,<br><br>Pranav</div></body></html>
