Talk:De Boor's algorithm

In the definition of the 0-th degree B-spline basis functions, the closed interval between u[i] and u[i+1] should be replaced by the half-open interval between u[i] and u[i+1].

Expressed otherwise, the article presently gives the requirement that we should have u[i] <= x <= u[i+1] but this requirement should really be u[i] <= x < u[i+1].

I would make this change myself, but I do not know how to do this in MathML.
