实际工作中，某个现象的发生或得到某种结果往往与某个或某些因素有关，但是这种关系又是不确定的，譬如，若用x表示某人的身高，用y表示他的体重，一般来说，当x越大时，y也倾向于越大，但由身高x并不能严格的决定体重y，只是从数据上可以看出这种趋势。回归分期就是用来研究具有这种特种变量之间的相关关系。本文详细介绍了回归分析的理论基础及其MATLAB实现方法，并通过实例分析证明了这种方法的合理性与可行性。

In practical situations , the occurrence of certain phenomenon or a result obtained from certain occa-sion is probably related to certain factors .However, it’s might be impractical to determine the nature of this rela-tion.E.g., x is the height of a person , and y is his weight .Usually, if x increases, y tends to increase too , but y cannot be precisely determined with x .Only there is a tendency visible with the data .Regression is utilized to solve this kind of co-relation problems .This paper introduces the basics of regression and its implementation with MATLAB.Case studies are provided to prove the rationale and feasibility of this method .
