摘要
介绍如何利用牛顿插值公式构造一个近似函数y≈N_n(x),设计出可在计算机上实现的算法并给出计算程序.
In this paper, the author introduced how to use Newton interpolation formula to structure an approximation function y≈Nn（x）. The algorithm that can be applied in computer was designed and the calculation program was also described in this paper.
