Frequently Asked Questions about pchip()
Is the pchip() 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 pchip() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.
Do I need to install MATLAB to use pchip()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The pchip() function requires no MATLAB® license or desktop software download.
What does pchip() do?
Shape-preserving piecewise cubic Hermite interpolation. Returns interpolated values, or a pp structure if xq is omitted. It is a MATLAB®-compatible curve fitting function available in SimLab with the same calling syntax as MATLAB® — typically: yq = pchip(x, y, xq).
Can I run pchip() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls pchip(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
