基于k-means的聚类编程，例如：随机选取k个中心点，经过计算每个点到k个中心距离的远近，将其归类。最后总的距离平方差最小，即停止。-Programmed based on k-means clustering, for example: randomly select k central point has been calculated for each point to the k center distances, will be classified. The final total distance squared difference between the smallest stops.
