WebIn numerical analysis, a cubic Hermite spline or cubic Hermite interpolator is a spline where each piece is a third-degree polynomial specified in Hermite form, that is, by its values and first derivatives at the end points of the corresponding domain interval.. Cubic Hermite splines are typically used for interpolation of numeric data specified at given … WebJul 18, 2024 · The cubic spline interpolation is a piecewise continuous curve, passing through each of the values in the table. The domain of s is in intervals of [a, b]. S, S’, S” are all continuous function on [a, b]. Here Si(x) is the cubic polynomial that will be used on the subinterval [xi, xi+1]. The main factor about spline is that it combines ...

WebCubic spline interpolation is the process of constructing a spline f: [x1, xn + 1] → R which consists of n polynomials of degree three, referred to as f1 to fn. A spline is a function defined by piecewise polynomials. Opposed to regression, the interpolation function traverses all n + 1 pre-defined points of a data set D.
