What does ode15s() do?

L-stable SDIRK2(3) solver for stiff ODEs. Use for stiff problems where ode45 is slow or fails (chemical kinetics, circuits with widely separated time constants). It is a MATLAB®-compatible ode solvers function available in SimLab with the same calling syntax as MATLAB® — typically: [t, y] = ode15s(f, tspan, y0).

Can I run ode15s() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls ode15s(), and run it. Execution happens locally in your browser — no data leaves your machine.
