二元切触有理插值函数的构造方法
Method of constructing bivariate osculatory rational interpolation function
摘要
Abstract
The methods of constructing bivariate osculatory rational interpolation function are mostly based on the continued fraction. But feasibility of the algorithm is conditional, the computation is large, and the degree of it is high. It constructs the bivariate osculatory rational interpolation function and extends it to vector-valued case, by means of the method of piecewise combination. It not only solves the existence problem of osculatory rational interpolation function, but also reduces the degree of rational function. Compared to other methods, the course of constructing function is formulary, the degree of rational interpolation function is lower, the feasibility of algorithm is unconditional, and the algorithm needs less computation and facilitates the practical application.关键词
