Spline maths

WebIn 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 degrees.. In the computer science subfields of computer … WebSplines are smooth piecewise polynomials that you can use to represent functions over large intervals, where it would be impractical to use a single approximating polynomial. …

Web20 May 2015 · A natural cubic spline with K knots is represented by K basis functions. One can start from a basis for cubic splines, and derive the reduced basis by imposing the boundary constraints. For example, starting from the truncated power series basis described in section 5.2, we arrive at where d k = ( X − ξ k) + 3 − ( X − ξ K) + 3 ξ K − ξ k.
