三次多项式局域插值样条

Cubic Polynomical Local Area Interpolating Spline

给出了曲线的一种困示方法，即用三次多项式局域插值样条来拟合原始数据．讨论了这种拟合的存在性、唯一性及逼近阶．

This paper presents a method for the graphical representation of curved,fitting of data with cubic polynomial local area interpolating splines, and deal with existence, uniqueness, approximation degree of the fitting.
