| 摘 要： | 插值法是工程实践中最常用的函数逼近方法,其方法就是利用有限个数据点来实现对整个函数的拟合.本文介绍了插值法的概念,进而对样条插值的概念和条件进行了阐述.三次样条插值和B样条插值是最常用的两种样条插值方法.本文着重对这两种方法进行了数学分析并基于MATLAB工具箱对其进行仿真实现.

| Abstract: | Interpolation method is the most common engineering practice function approximation method,which uses a finite number of data points to achieve the fitting of the function.This paper introduced the concept of interpolation,then described the concept and conditions of spline interpolation.The most common spline interpolation methods,cubic spline interpolation and B-spline interpolation,were discussed mainly by means of mathematical analysis and simulation based on MATLAB toolbox. |
