Hi Zulko,
firstly, thank you for writing ddeint!. I am trying to solve an initial value problem for the case that x''(t) is known and depends on x(t-dt). In scipy without the delay I do this as following:
def function(z, t): return np.array([x''(z[1]), z[0]])
then odeint returns an np.array of [x',x]
However in ddeint this seems difficult as I cannot index z. Any help would be appreciated.
Cheers!
Well more than a year later: Does the example in https://computationalmindset.com/en/mathematics/solving-delay-differential-equations-in-python-using-numerical-methods.html help?
