I want to make bsplines in matlab, so I can create the images below.

Definition 2 (Cox de Boor recursion formula). Univariate B-splines N R - R are defined recursively from a polynomial degree q E N and a knot vector : Ng.i(E)= otherwise (2.8a) 0 for j-0 and i-n +q, and i+j+1 i+j+1 i+1 for j = 1.2, . . . . q and i = 1, . . . , n + q-j, and where we define 1,- 0 Univariate B-splinesa mined by the polynon ines from different polynomial degrees and Some important properties of B-splines are contained in the following Theorem 1. B-splines uith knot vector-and polynomial degree q fulfill amples of B-spl vectors are shown in Figure 2.3 Definition 2 (Cox de Boor recursion formula).
