Stable Evaluation of Box-Splines
Numerical Algorithms 14 (1997) 4, J.C. Baltzer, pp. 377-382
The most elegant way to evaluate box-splines is by using their recursive definition. However, a straightforward implementation reveals numerical difficulties. A careful analysis of the algorithm allows a reformulation which overcomes these problems without losing efficiency. A concise vectorized MATLAB-implementation is given.
