摘要
利用有理基函数给出了构造二阶二元混合切触有理插值函数的一种方法.该方法可以简便地计算二阶二元混合切触有理插值函数,并将它成功地推广到高阶多元混合切触有理插值函数的构造中;最后的数值例子表明该方法的有效性.
This paper provides a way of constructing bivariate blending osculatory rational interpolants of two order. The method can compute bivariate blending osculatory rational interpolanting function of two orders simply and be generalized to multivariate blending osculatory rational interpolants of higher orders successfully. The formula are flexible and convenient to be used in practice. Finally, the examples suggest the method is powerful.
