I tried rewriting it to be in ps, and got the same error, which is:

error: Solving has not been successful. The iterative integration loop exited at time t = 0.000000 before endpoint at tend = 100.000000 was reached. This may happen if the stepsize grows smaller than defined in vminstepsize. Try to reduce the value of "InitialStep" and/or "MaxStep" with the command "odeset".

Is vminstepsize something I can set?

Also, what is eps?

Thank you very much.

What exactly do you mean doesn't work? Does it quit with an error?

You could possibly try another solver from odepkg, e.g. ode2r (off the top of my head)
