In fact, each B-spline basis function is non-zero on a few adjacent subintervals and, as a result, B-spline basis functions are quite local. Let U be a set of m + 1 non-decreasing numbers, u. The knots can be considered as division points that subdivide the interval [ u. To define B-spline basis functions, we need one more parameter, the degree of these basis functions, p. The i-th B-spline basis function of degree p, written as N. The above is usually referred to as the Cox-de Boor recursion formula. This definition looks complicated; but, it is not difficult to understand.
