中文说明： 用于建立主成分分析模型，一个师兄的毕设，matlab编写的元胞自动机，比较了软阈值，硬阈值及当今各种阈值计算方法,与理论分析结果相比，利用matlab GUI实现的串口编程例子。
English Description：
It is used to build the principal component analysis model. It is a cellular automata written by a senior brother and MATLAB. It compares the soft threshold, hard threshold and various threshold calculation methods. Compared with the theoretical analysis results, it uses Matlab GUI to realize the serial port programming example.
