sol = dde23(ddefun, delays, history, tspan)
sol = dde23(ddefun, delays, history, tspan, options)
dde23 solves delay equations where each delay is a positive constant lag. The derivative function is called as f(t,y,z), where each column of z is a delayed state.
| Item | Details |
|---|---|
| Delay type | Positive constant lags. |
| Callback | f(t,y,z) |
| History | Scalar, vector, solution structure, or function depending on the call form. |
| Solution | sol structure with x, y, yp, solver, and deval interpolation. |
