matlab具有强大的数值计算能力，生成的图形简便，直观。该文件中包含了一些matlab中数值计算方面的例程，包含了一些原创程序。(matlab numerical calculation has powerful ability to generate graphics simple and intuitive. The document contains a number of numerical computing matlab routine, including a number of original procedures.)

余弦分析采用最小二乘法，以适应一个正弦波的时间序列。余弦分析通常用于生物时间序列分析，演示predictible的节奏。这种方法可用于一个不平等的间隔时间序列。(Cosinor analysis uses the least squares method to fit a sine wave to a time series. Cosinor analysis is often used in the analysis of biologic time series that demonstrate predictible rhythms. This method can be used with an unequally spaced time series.)

利用ARMA（3,2）模型和davenport功率谱 对脉动风进行模拟， 在叠加平均风，得到风序列(Use ARMA (3,2) model and the davenport For fluctuating wind simulate Superimposed mean wind, get wind sequence)

主要基于Matlab平台开发的，特征提取仿真程序，主要用于生理信号的特征提取。(Mainly developed based on Matlab platform, feature extraction simulation program, mainly for physiological signal feature extraction.)

说明：  这是黑龙江大学自控理论专业同学在最优估计课程当中用matlab编写的gw算法!(This is the theory of controlled Heilongjiang University students in professional courses optimal estimate prepared by using Matlab algorithms gw!)

小波分析，对振动信号的分析，用于提取故障特征。(Wavelet analysis, the analysis of vibration signals for extracting fault feature.)
