关于kalman滤波的一个比较有代表性的例子，程序中把没有加高斯噪声和加过高斯噪声后进行滤波后的图形用不同颜色的曲线画在了一个图上，便于比较和理解(Kalman filter on a more representative example of the program to add Gaussian noise and processing not been filtered Gaussian noise after the graphic curves of different colors painted on a map, to facilitate comparison and understanding)

灰色预测是就灰色系统所做的预测。所谓灰色系统是介于白色系统和黑箱系统之间的过渡系统。其具体的含义是:如果某一系统的全部信息已知为白色系统，全部信息未知为黑箱系统，部分信息已知，部分信息未知，那么这一系统就是灰色系统。(Grey prediction is the prediction of grey system. The so-called grey system is a transitional system between the white system and the black box system. Its concrete meaning is: if all information of a system is known as a white system, all information is unknown as a black box system, some information is known, and some information is unknown, then this system is a grey system.)

最小二乘支持向量机算法程序，可用于解决多类分类问题(Least squares support vector machine procedures that can be used to solve multi-class problem)

对于给定的结构振动响应数据（时间序列信号）， 该程序可以分解成多个订单这些响应信号 小波子信号，然后计算出分信号能量spectum。 (For a given structural vibration response data (time series), the program can be decomposed into multiple sub-orders for the response signal wavelet signal, and then calculate the sub-signal energy spectum.)
