在机器学习中经常会用到支持向量机，该代码是再使用支持向量机前对数据进行主成分分析的代码(We often meet support vector machine in machine learning , the code is about the principal component analysis befor using support vector machine (SVM).)

对于高斯脉冲信号，在光纤传输过程群速度色散是否会导致脉冲展宽(For the Gaussian pulse signal, whether the velocity dispersion in the fiber transmission process will lead to pulse broadening)

基于FFT的频谱分析程序，包含感应电机定子电流数据，可直接运行(FFT based spectrum analysis program, including the induction motor stator current data, can be directly run)
