说明：  基于奇异谱的齿轮箱振动信号分析，含主程序及熵值函数。(The vibration signal analysis of Gearbox Based on singular spectrum includes main program and entropy function.)

自己写的几个matlab的函数，自己处理数据是常用。有滤波函数、平移函数等。处理后新生成的数组和原数组大小相同，行列特性也相同。(Himself wrote several matlab functions, deal with their own data is commonly used. There are filtering function, translation function, and so on. The new array is generated after treatment and the original array the same size, the ranks of features are the same.)
