此源程序为层次聚类中AGNES聚类法算法部分，测试数据须自己输入，测试前最好先看下源码

测试数据只有2个属性，可根据自己需求修改数据结构体属性个数，与对象间欧式距离计算函数

本源码若算法复杂度有可改进的地方或有BUG请高手指出，计算500条以上的数据时须耐心等待结果

-The source code for the hierarchical clustering algorithm in part AGNES clustering method, the test data required to enter their own test before the best look at the source under test data only two properties, according to their property needs to modify the number of data structures, and objects evaluate the function of the Euclidean distance between the source if the complexity of the algorithm are areas of improvement or a BUG, ​ ​ please master pointed out that more than 500 data calculated to be patient and wait for the results
