![]() ![]() In fact, the Schönberg-Whitney theorem states that, if you choose the $i$-th interpolation node $\xi_i$ to lie in the interior of the support of the $i$-th B-spline function, then the resulting nodes $(x_i)$ are unisolvent. However, choosing the Gréville abscissae is not the only possible choice.

See for instance the definition of Gréville abscissae, which are just particular interpolation nodes, here. For a spline space, however, it is common to choose the interpolation nodes as certain averages of the knots. For a sequence of knots, $(t_1, \ldots, t_m)$, a spline is a function which is polynomial when restricted to each nonempty knot span $(t_i, t_)$ and satisfies some additional continuity assumptions in the knots.
