采用MATLAB的线性回归分析

Linear Return Analyzed with MATLAB

回归分析是把工程和科学实验数据拟合为线性函数,以反映变量间的相互关系。为此,通过最小二乘法推定系数,构造其矩阵。并用MATLAB语言编制相关程序,实现其线性回归分析。该程序可用于数据的经验公式拟合。

The regressive analysis is that the data of engineering and scientific experiment are fitted into linear function to correspond to the mutual relationship among the variable. So, the matrix was constructed with deducing coefficients of least-square method. Correlation program was programmed with MATLAB to realize its linear regressive analysis. This program is also used for fitting into the experience formula on data.
