Curve Fitting
pchip() is a MATLAB®-compatible curve fitting function for shape-preserving piecewise cubic hermite interpolation. returns interpolated values, or a pp structure if xq is omitted. Run it online in your browser with SimLab — free, no install, no license required.
Shape-preserving piecewise cubic Hermite interpolation. Returns interpolated values, or a pp structure if xq is omitted.
Syntax
yq = pchip(x, y, xq)
pp = pchip(x, y)

Frequently Asked Questions about pchip()
Is the pchip() function free to use in SimLab?
Yes. SimLab is 100% free — no signup, no license, and no usage limits. You can run pchip() and 510+ other MATLAB®-compatible functions directly in your browser at simulations4all.com/simlab.
Do I need to install MATLAB to use pchip()?
No. SimLab runs entirely in your web browser with zero installation. The pchip() function works without any MATLAB® license or 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. Execution happens locally in your browser — no data leaves your machine.
