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.
