一种高效的聚类算法给定要聚类的N的对象以及N*N的距离矩阵(或者是相似性矩阵), 层次式聚类方法的基本步骤(参看S.C. Johnson in 1967)如下:-An Efficient Algorithm for the cluster must be the object of N and N * N distance matrix (or similarity matrix), the hierarchical clustering method the basic steps (see

使用c语言打印n阶螺旋矩阵，算法较为浅显易懂-N order to print using c language spiral matrix, the algorithm is more easy to understand
