摘　　要：插值方法是"数值分析"课程中非常重要的教学内容,也是数值微分、数值积分和常微分方程初值问题数值解的基础。本文探讨了插值问题的基本思想和常用的几种插值方法,重点比较了代数多项式插值方法。利用Matlab在科学计算中的优势,在实践教学中用Matlab进行了插值方法的对比教学研究。结果表明:通过比较教学使学生较快掌握了插值算法知识点,并能应用于实际科学研究项目之中,取得了较好的教学效果。Interpolation method is the important teaching content in Numerical Analysis courses, and is foundation for numerical integration and numerical differentiation and initial value problems in ordinary differential equations. This paper discusses the basic idea of interpolation problem and several common interpolation methods, and mainly compares the polynomial interpolation algorithms. Utilizing the superiority of Matlab in numerical calculation, com- parative teaching of interpolation algorithms is presented by using Matlab in teaching practice. The results show that the students can quickly comprehend the knowledge and conduct the applicable verification in the comparative reac- hing. The pretty teaching result is got.
