Cubic hermite interpolant

WebThe PCHIP interpolant takes non-equispaced data and interpolates between them via cubic Hermite polynomials whose slopes are chosen so that the resulting interpolant is monotonic; see Fritsch and Carlson for details. The interpolant is C 1 and evaluation has 𝑶(log(N)) complexity. An example usage is as follows: 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 …
