Call a solver with one output to get a solution structure. The structure stores accepted internal steps; array outputs such as [t, y] use requested or refined output points. Use deval to evaluate the solution structure at additional times.
| Task | Call | Notes |
|---|---|---|
| Interpolate | deval(sol, tq) | Evaluation points must stay inside the solution interval. |
| Get derivatives | [y, yp] = deval(sol, tq) | Derivative output follows the same column layout as y. |
| Continue | odextend(sol, odefun, tfinal) | Builds a new solution structure on the extended interval. |
Use odextend to continue an integration from the final state while preserving solution metadata and events.
sol = ode45(@(t,y) -y, [0 1], 1);
values = deval(sol, [0 0.25 0.5 1])sol = ode45(@(t,y) -y, [0 0.5], 1);
extended = odextend(sol, @(t,y) -y, 1);
value = deval(extended, 1)| Version | Description |
