Take care that the ode requires the function being at least continuous
and differentiable
If your input signal has singularities (points where it nos
differentiable) you must stop the integration at this point and restart
it just after taking the last state value as the intial point for the
second run.

Dear fellows,
my goal is to solve numerically an ODE which contains a time-dependent
parameter using 'ode'. I get a confusing result depending on whether the signal
(it's called h) is on for 10 or 20 seconds. The two results are attached.
Regardless of the model and the code, there should be a response in the
variable w as soon as h switches from 0 to 1. I can provide any other
information as needed.
Should I use bugzilla to report this? I am not doing this very often, so I need
some instruction how to proceed.
Thank you and best regards,
Peter
