摘要
通过分别介绍拉格朗日插值法、分段线性插值法和三次样条插值法的理论知识,结合数学软件Matlab编程工具,对机床加工零件问题展开研究。针对3种插值方法所得到的图像曲线,比较它们的适宜性,分析和判断哪一条曲线最能反映出实际问题中的关系。
Lagrange interpolation, piecewise linear interpolation and cubic spline interpolation methods of theoretical knowledge is focused on, combined with mathematical software Matlab programming tool for machining parts problems to study and compare their suitability of the curves obtained by the three interpolation methods. At the same time, it is analyzed and determined which curve best reflects the relationship between the actual problems.
