基于kdtree的kmeans聚类方法。

包括三个文件 kdtree.m kmeans.m sqdist.m

在kdtree的基础上用kmeans算法对数据进行聚类，能够提高聚类的精度。-kmeans based on kdtree

基于kdtree的kmeans聚类算法，在选择最近邻中心点时使用kdtree的检索功能，提高了检索效率，特别是当k较大时，效果明显提升-kmeans clustering algorithm based on kdtree，used in selecting the center point of the nearest neighbor the kdtree retrieval function, and improve the retrieval efficiency has improve
