摘要
以多元多项式插值的代数理论为工具,给出多元情形下Cauchy型插值函数的表达式与有理插值的存在条件,得到了与一元情形相似的结论.
This paper studied multivariate rational interpolation of Cauchy type with the help of the algebraic theory about multivariate polynomial interpolation. It's expression and existence condition was given. The conclusion obtainal is similar to univariate Cauchy rational interpolation.
