WebMar 24, 2024 · Spline Download Wolfram Notebook A piecewise polynomial function that can have a locally very simple form, yet at the same time be globally flexible and smooth. … WebMar 17, 2024 · That was a bit negative. However, it is not too difficult to apply the formulae in this answer and this answer to derive a routine that generates not-a-knot cubic splines (as was astutely observed by CA Trevillian and others in the comments.). Of course, one can use SparseArray[] + LinearSolve[] to solve the underlying tridiagonal system, so I'll …

The degree of the spline is defined by p = m − n − 1, so m = 9, and you have a knot vector with twelve elements ( m = 11 ). If the knots are uniformly within 0 … 1, except with start and end knots, the knot vector is. T = { t 0, t 1, t 2, …, t 9, t 1 0, t ...
