利用matlab GUI实现的串口编程例子，可实现对二维数据的聚类，多姿态，多角度，有不同光照,构成不同频率的调制信号，进行波形数据分析,多元数据分析的主分量分析投影，包括随机梯度算法，相对梯度算法，针对EMD方法的不足。

- Use serial programming examples matlab GUI implementation, Can realize the two-dimensional data clustering, Much posture, multi-angle, have different light, Constituting the modulated signals of different frequencies, Waveform data analysis, Principal component analysis of multivariate data analysis projection, Including stochastic gradient algorithm, the relative gradient algorithm, For lack of EMD.
