I suggest that an optional argument for ode would be a set of
dates where the function is singular, so ode manages this by
itself. What do you think?<br>

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.<br>

<pre wrap="">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
