WebSep 29, 2024 · s = spline (x, y, 600); John D'Errico on 29 Sep 2024. Note that this is rather noisy looking data, and it has large changes in slope. That makes a cubic spline a terribly poor choice to model that curve, even if it appears it survived the process and produced a monotonic curve. Using a higher order interpolant to model noise is often a bad idea.
