数据EOF分析，海洋气象常用。将长时间，多空间点数据分解成时间序列和空间序列。进行数据的时空分析。(Used for EOF analyse)

平行坐标轴是可视化的一种传统方法，用于模式识别聚类等，数据是‘鸢尾花数据集’，有较好的分类效果。(Parallel to the axis is a traditional way to visualize, used for clustering and pattern recognition, data is the iris data set, have better classification effect.)

一个很好的扩频产生程序，可以帮你完成扩频通讯。(Spread spectrum have a very good program, can help you achieve spread-spectrum communications.)

短时傅里叶变换可以用差分模式来实现，对书上的运算式做了稍许的改变。改变-计算差分序列的第一列数据时用的是第一列的元素减去当前行的最后一列元素。原算法中采用的是第一列元素减去下一行第二列元素。原算法加窗之后结果比较好，不加窗时结果误差很大，而改变之后的算法不加窗效果依然很好。(Short time Fourier transform can be used to achieve the differential mode of expression on the book made a slight change. Change- calculating the difference sequence of the data with the first column is the first column of the matrix by subtracting the current element in the last column of row. Is used in the original algorithm subtracts the elements of the first column of the next row and the second column elements. After the results of the original algorithm windowed better, when the results window without great error, and after changing algorithms no window effect is still very good.)

声音时频分析的小程序，可以直接使用，可供初学者参考利用。(Sound frequency analysis procedures can be used directly reference for beginners to use.)

基于2阶消失矩的Coifman小波基函数的2维MRTD电磁散射正演模型，吸收边界为PML。(Based on 2 vanishing moments of the Coifman wavelet function of 2-D MRTD forward model of electromagnetic scattering, absorbing boundary for the PML.)

模式识别中的bayes判别分析算法，进行逐步线性回归，小波包分析提取振动信号中的特征频率。( Pattern Recognition bayes discriminant analysis algorithm, Stepwise linear regression, Wavelet packet analysis to extract vibration signal characteristic frequency.)
