Clearly, Lagrange interpolation nodes are used the more the number of interpolation polynomial higher.

显然，Lagrange插值中使用的节点越多，插值多项式的次数就越高。

There are substantial relation between the interpolation and approximation of functions.The interpolation polynomial is regarded as the important tool of achieving approximation of function.

HereM=min{p, u + q + 1 }, and u + q is the degree of Lagrange interpolation polynomial.
