说明：  一些数值计算用的MATLAB代码,适合初学MATLAB和数字计算的人使用,根据MATLAB的矩阵思想编写，对初学者更好的把握MATLAB编程思想很有用(Some numerical calculation using MATLAB code, suitable for novice MATLAB and digital computing use, according to the ideological preparation of MATLAB matrix, for beginners to grasp a better MATLAB programming ideas useful)

The method works as follows. 1. For a data set with dimensionality, d, compute the variance of data in each dimension (column). 2. Find the column with maximum variance call it cvmax and sort it in any order. 3. Divide the data points of cvmax into K subsets, where K is the desired number of clusters. 4. Find the median of each subset. 5. Use the corresponding data points (vectors) for each median to initialize the cluster centers.
