摘要
一类多元多项式的有效赋值方法张晓鹏（西北大学数学系，西安７１００６９；作者，男，３２岁，讲师）矩形域和立方体上定义的多元多项式是逼近论和计算机辅助设计等方面应用很广泛的函数形式［１．２］，因而人们很关注它的有效赋值问题．本文对矩形域上的Ｂｅｒｎｓｔｅ...
This paper furnishes an efficient algorithm and its evaluation scheme for Bernstein polynomials over rectangles and cubes, which is faster in one degree than de Casteljau algorithm in the number of multiplications and is also stable.
