fuzzy_cluster模糊聚类分析，本函数使用的是直接聚类法，直接输出聚类信息，无返回值

输入参数data是需要分类的数据，将会对data的列分类，请输入数据前把需要分类的向量按列保存到矩阵data

输入参数numda是分类的分类点，如果不知道可以先省略，系统默认1-0依次减小用以方便判断分割点，然后用户再细分-　Fuzzy_cluster fuzzy clustering analysis, the function uses the clustering method is direct, direct output clustering information, no return value　input parameter data is needed to classify data, classification of data will be listed, enter the data before the need saved by the column vector classification matrix data　to the input parameters numda profile classification point is, if you do not know can be omitted, in order to reduce the system default 1-0 split point for easy judgment, then the user is subdivided
