| 摘 要： | 本主要讨论了反插值的计算方法题，从两个自然的想法入手，用两种不同的思想方法构造了反插值的算法，即利用f(x)的插值多项式进行反插以及直接构造f^(x)的插值多项式进行反插，最后用一个具体的例子用上述两种方法进行编程序计算，比较其结果与精确值的差异。

| Abstract: | In this paper, inverse interpolation is mainly discussed. Two different methods are used to solve the problem. The first is to use interpolation of f(x); in the second we directly set up the interpolation polynomial of f-1(x) . At last, the two methods to solve an example about inverse interpolation is used. Further more, the results of two methods with the exact solution and their errors are compared. |
