This means that its polynomial pieces have degree < Multiplicities govern the smoothness of the spline across the knots, as detailed below. But knots are different from breaks in that they may be repeated, i.e., t need not be Roughly speaking, such a spline is a piecewise-polynomial of a certain order and withīreaks t( i). When the coefficients are 2-vectors or 3-vectors, f is a curve in The coefficients may be (column-)vectors, matrices, even See Multivariate Tensor Product Splines for a discussion A univariate spline f is specified by its nondecreasing knot sequence t and by its B-spline coefficient sequenceĪ.
