WebApr 6, 2015 · PCHIP is a FORTRAN77 library which can construct a piecewise cubic Hermite interpolant to data, and carry out various related operations, by Fred Fritsch. … 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 …
Webmials. Instead, one can construct the Hermite polynomial using a Newton divided-di erence table, in which each entry corresponding to two identical interpolation points is lled with the value of f0(x) at the common point. Then, the Hermite polynomial can be represented using the Newton divided-di erence formula.
