无监督混合高斯模型（GMM）的EM估计，含两篇IEEE论文的源码(This is a set of MATLAB m-files implementing the mixture fitting algorithm described in the paper M. Figueiredo and A.K.Jain, "Unsupervised learning of finite mixture models", IEEE Transaction on Pattern Analysis and Machine Intelligence, vol. 24, no. 3, pp. 381-396, March 2002.)

The circular convolution, also known as cyclic convolution, of two aperiodic functions (i.e. Schwartz functions) occurs when one of them is convolved in the normal way with a periodic summation of the other function.

用EWMA（garch（1，1））模型进行计算，rolling window的形式(use the method of rolling window size equals to 250, adopt EWMA model which also calls Garch(1,1) to calculate the Value at Risk)

在风的特性、风与结构的相互作用和风荷载的计算理论分析的基础上,利用斜拉索上点的受力情况对脉动风场进行模拟,基于谐波合成法的计算公式(haracteristics of the wind, the calculation basis for the interaction of wind load wind theory and structure analysis, the use of the forces on the cable-stayed point of fluctuating wind field simulation, based on a formula to calculate the harmonic synthesis)

一个将32路64kbps信息流合成一个基群的复用模块和相应的解复用模块，要能观察合成或分解后信息流的一致性，演示的最小时间刻度为时隙（一次采样，即1/8000秒）。(64kbps would be a 32-way flow of information into one group based reuse modules and the corresponding de-multiplexing module, to be able to observe the post-synthesis or decomposition of the consistency of the flow of information to demonstrate the minimum time scale for the time slot (one sample, that is, a/8000 seconds).)

sand法求2幅图片的光流，在brox法基础上的改进，包括文章和代码(Method 2 sand picture of optical flow, based on the law in brox improvements, including articles and code)
