Monotone interpolation can be accomplished using cubic Hermite spline with the tangents modified to ensure the monotonicity of the resulting Hermite spline. An algorithm is also available for monotone quintic Hermite interpolation. There are several ways of selecting interpolating tangents for each data point. This section will outline the use of the Fritsch–Carlson method. Note that only … WebI shall discuss the three which I have most experience with. Recall that given points ( x i, y i), i = 1 … n, and assuming no two x i are the same, one can fit a piecewise cubic Hermite interpolant to the data. (I gave the form of the Hermite cubic in this previous answer .) To use the notation of that answer, you already have x i and y i and ...
