Frequently Asked Questions about ode15s()

Is the ode15s() function free to use in SimLab?

The browser workspace requires no MATLAB® license or installation. Connected features require network access and may have account, tier, availability, or usage limits. You can open ode15s() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.

Do I need to install MATLAB to use ode15s()?

No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The ode15s() function requires no MATLAB® license or desktop software download.

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. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
