说明：  通过直接分析声音文件得到最大似然估计法下的混响时间和混响时间的图像，房间空间的参数来自AIR数据库，数据库里面有多种房间形式的参数形式。(Through the direct analysis of sound files, the images of reverberation time and reverberation time under the maximum likelihood estimation method are obtained. The parameters of room space come from air database, which has many kinds of room forms.)

This demo tracks cars in a video by detecting motion using optical flow. The cars are segmented from the background by thresholding the motion vector magnitudes. Then, blob analysis is used to identify the cars.

维纳滤波器设计，改变滤波器阶数N和信号长度取值L，观察两者对实验结果影响(Wiener filter design, changing the order of the filter length N and the signal value L, were observed both on experimental results)

基于形态学方法的图像分割文件，.m的源代码(Based on morphological image segmentation file,. M of the source code)

gold序列的生成 PN序列Gold序列极好的自相关性 生成64位的PN序列 (Gold sequence generated PN sequence gold sequence excellent correlation )

基于电力系统中的潮流编写的电力系统回路阻抗法 以更好的解决电力系统中的潮流问题(Based on the trend of power system loop impedance power system written law in order to better solve the power system of the power flow problem )

根据经纬度计算两点间的球面距离（两种方法基于球面余弦公式，基于Haversine公式）、计算方位角。(calculate spherical distance and azimuth angle by Latitude and Longitude)

说明：  RLC游程编码程序,matlab可直接运行(RLC routine)

运用MATLAB进行空间自回归以及空间聚合程度计算，空间聚类的基本操作。(MATLAB is used for spatial autoregression and the calculation of spatial aggregation degree, and the basic operation of spatial clustering.)
