Changed a minus to a plus in the equation since the source this cited had a plus and not a minus. |

Line 23:
Due to the spline locality property,
:<math> \mathbf{s}(x) = \sum_{i=\ell-n}^{\ell} \mathbf{d}_i N_i^n(x) </math>
So the value <math>\mathbf{s}(x)</math> is determined by the control points <math> \mathbf{d}_{\ell-n},\mathbf{d}_{\ell-n+1},\dots,\mathbf{d}_{\ell} </math>; the other control points <math>\mathbf{d}_i</math> have no influence.
