针对案例数据，用matlab软件对数据进行极差法归一化处理；并使用主成分分析法分析选定成分的特征值贡献率，从而为进行下一步数据分析做一些准备。(According to the case data, the data is normalized by range method with MATLAB software, and the contribution rate of the selected components is analyzed by principal component analysis, so as to make some preparations for the next step of data analysis.)

PCA主成分分析算法用于人脸识别的例子。此算法是基于矩阵特征值的排序而提取出主要成分的。(PCA principal component analysis algorithm for face recognition example. This algorithm is based on the ranking of the matrix eigenvalue extracted principal components.)

Defining the plot Function for the DocPolynom Class The MATLAB plot function creates line graphs. The overloaded plot function selects the domain of the independent variable to be slightly larger than an interval containing all real roots. Then the polyval method is used to evaluate the polynomial at a few hundred points in the domain:

本代码是关于MIMO的空时分组码的仿真，内容比较全面。(The code is on the MIMO space-time block code simulation, content more comprehensive.)
