Witryna16 gru 2024 · 在处理某些插值问题的时候 会要求插值函数具有一定的“光滑度” 即在某点处的导数满足一定的条件 这类插值问题称为Hermite插值问题 如蓝色为原函数，红色为插值函数 p1只是经过了插值点 p2多了一个条件，在插值点… WitrynaCompare 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.
