利用台湾大学教授所开发的支持向量机工具箱做预测和分类算法(prediction using svm)

matlab中编的基于遗传算法的转子故障特征选择的小程序，新手程度，仅供参考(matlab in the series based on genetic algorithm rotor fault feature selection of small programs, novice level, for reference only)

S 变换是 Stockwell（1996）等提出的一个时-频分析方法，它结合了短时 Fourier 变换和小波变换的特点，能够完全无损地实现逆变换。(S-transform is a time-frequency analysis method proposed by Stockwell (1996). It combines the characteristics of short-time Fourier transform and wavelet transform, and can realize inverse transform completely without loss.)

对一段振动信号emd分解后，求每个分量的峭度值，选取峭度最大的分量，求其包络谱，能够明显看出特征频率。(After a period of vibration signal emd decomposition, seeking kurtosis value of each component, the largest component of kurtosis, seeking its envelope spectrum, can obviously see that the characteristic frequency.)
