Author Ordinary differential equation with one delay
Nicolas Michoux

Hello,
My problem concerns the resolution of the kinetic equation:

dC(t)/dt = a.Cin(t) - b.C(t) + e.C(t-tau)

where a,b,e are constants to be optimized and Cin(t) is
a vector. The ode functions are not usable because of the
third term in (t-tau). I am not sure that this formulation
is compatible with the dde function too, but maybe I am
wrong.
A suggestion, anyone ??
Thank you very much by anticipation.
Best regards.

I think you can use dde23
