In mathematics, a spline is a special function defined piecewise by polynomials. In interpolating problems, spline interpolation is often preferred to polynomial interpolation because it yields similar results, even when using low degree polynomials, while avoiding Runge's phenomenon for higher … See more The term "spline" is used to refer to a wide class of functions that are used in applications requiring data interpolation and/or smoothing. The data may be either one-dimensional or multi-dimensional. Spline functions for … See more We begin by limiting our discussion to polynomials in one variable. In this case, a spline is a piecewise polynomial function. This function, call it S, takes values from an interval [a,b] and … See more It might be asked what meaning more than n multiple knots in a knot vector have, since this would lead to continuities like at the location of … See more For a given interval [a,b] and a given extended knot vector on that interval, the splines of degree n form a vector space.

In the mathematical field of numerical analysis, spline interpolation is a form of interpolation where the interpolant is a special type of piecewise polynomial called a spline. That is, instead of fitting a single, high-degree polynomial to all of the values at once, spline interpolation fits low-degree polynomials to small subsets of the values, for example, fitting nine cubic polynomials between each of the pairs of ten points, instead of fitting a single degree-ten polynomial to all of them. Sp… Web15 Jun 2024 · An S-spline curve is given by (1) P ( t) = ∑ i = 1 n P i B i ( t) ∑ i = 1 n B i ( t) where (2) B i ( t) = β i B t → i ( t). β i is a scalar constant which ensures the property of partition of unity, and can be computed using the knot refinement algorithm.
