Description: Matlab中没有现成的Lagrange插值函数，必须编写一个M文件实现Lagrange插值。
设n个节点数据以数组x0,y0 输入（注意Matlat的数组下标从1开始），m 个插值点以数组 x输入，输出数组y 为 m个插值。
编写一个名为lagrange.m的M文件。-Matlab is not off-the-shelf Lagrange interpolation function, we must realize the preparation of an M file Lagrange interpolation. N nodes based data to an array of x0, y0 input (Note Matlat subscript of the array starting at 1), m a x interpolation points to the array input and output array y for m months interpolation. Lagrange.m the preparation of a M-file.

Description: 考虑在一个固定区间上用插值逼近一个函数。显然，Lagrange插值中使用的节点越多，插值多项式的次数就越高。我们自然关心插值多项式增加时，Ln(x)是否也更加靠近被逼近的函数。龙格(Runge)给出的一个例子是极著名并富有启发性的。-Considered at a fixed interval on a function approximation using interpolation. Clearly, Lagrange interpolation nodes are used the more the number of interpolation polynomial higher. We are naturally concerned about the increasing interpolation polynomials, Ln (x) is also closer to being a function approximation. Runge (Runge) give an example of a well-known and are very stimulating.
