Frequently Asked Questions about ppval()

Is the ppval() 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 ppval() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.

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

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

What does ppval() do?

Evaluate a piecewise-polynomial structure (from mkpp/pchip/spline) at query points. It is a MATLAB®-compatible curve fitting function available in SimLab with the same calling syntax as MATLAB® — typically: y = ppval(pp, xq).

Can I run ppval() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls ppval(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
