SpletCompare the interpolation results produced by spline, pchip, and makima for two different data sets. These functions all perform different forms of piecewise cubic Hermite interpolation. Each function differs in how it computes the slopes of the interpolant, leading to different behaviors when the underlying data has flat areas or undulations. Spletpchip interpolates using a piecewise cubic polynomial P ( x) with these properties: On each subinterval x k ≤ x ≤ x k + 1 , the polynomial P ( x) is a cubic Hermite interpolating polynomial for the given data points with specified derivatives (slopes) at the interpolation points. P ( x) interpolates y , that is, P ( x j) = y j, and the ...
