用matlab实现灰色序列预测GM(1,1)，其中级比的判断采用手工判断。(Using matlab to achieve gray sequence prediction GM (1,1), one class than the judge to determine manually.)

matlab code is used the many purpose

说明：  数值随机化算法计算圆周率，面积法投点计算，利用matlab，绘出不同投点下的计算结果(Randomized algorithm to calculate the value of pi, cast-point calculation of area method, using matlab, plot points under different investment results)

面阵阵列天线二维方向图仿真，代码简单易懂(The two-dimensional surface bursts columns antenna pattern simulation, the code is easy to understand)

Video IO toolbox for matlab. 用directshow做的，比matlab自己的video IO函數強很多。(Video IO toolbox for matlab. Do with DirectShow than matlab own video IO function a lot stronger.)

This function is for training a codebook for vector quantization. The data set is split to two clusters, first, and the mean of each cluster is found (centroids). The disttance of each vector from these centroids is found and each vector is associated with a cluster. The mean of vectors of each cluster replaces the centroid first. If the total distance is not improved substantially, The centroids are each split to two. This goes on untill the required number of clusters is reached and the improvement is not substantial.
