摘要
本文给出一种新型的构造三元切触有理插值的方法,用此方法构造插值函数简单易行,还可以降低插值函数分母或分子次数,比常规的连分式方法计算量小,且算法可行性无条件限制,能推广到多元函数的情形,具有一定的普遍适用性和实用价值。
In this paper, the trivariate osculatory rational interpolating function was constructed by the method of convex combination. For osculatory rational interpolating function having been constructed, its number of times could be reduced by choosing parameters. This method of constructing osculatory rational interpolating function was easy and had im- mense application foreground. The discussion of constructing osculatory rational interpolation unconditionally had practical v^ue.
