摘要：

The purpose of this paper is to present an efficient algorithm for evaluation of interpolating polynomials. This algorithm is analogous to an algorithm for the evaluation of Bernstein polynomials known as the de Casteljau algorithm in the computer-aided geometric design literature. The authors also derive a forward difference formula for P//n(x,y) which is a two-dimensional analog of the forward difference representation of the interpolating polynomial for a function defined on equally spaced points on the real line.
