1直接复制在MATLAB中运行
%clusterdata函数
clc,

yangben = load('ca.txt');  %提取样本
芹菜根
t = size(yangben);      %求矩阵行,列数
t1 = t(1);
t2 = t(2);
ca =yangben(:,2:t2-1);  %这里是调用100*9的实验数据(即去除第一列和最后一列)
E=yangben(:,t2);
E(find(E==2))=1;
E(find(E==4))=2;
yangbenjieguo=E(:,:);    %为了进行正确率的计算,必须一致。这里是替换并提取原始结果矩阵a
X=ca;
[class,type]=dbscan(X,2,[])
2.数据,请复制保存为ca.txt.  第一列是编号,最后一列是结果。聚类结束后,请注意转换结果

3clusterdata函数,MATLAB中输入 type clusterdata 可以查看
function T = clusterdata(X, varargin)
%CLUSTERDATA Construct clusters from data.
%  T = CLUSTERDATA(X, CUTOFF) constructs clusters from data X.
%  X is a matrix of size M by N, treated as M obrvations of N
%  variables.  CUTOFF is a threshold for cutting the hierarchical
%  tree generated by LINKAGE into clusters. When 0 < CUTOFF < 2,
%  clusters are formed when inconsistent values are greater than
%  CUTOFF (e INCONSISTENT). When CUTOFF is an integer and CUTOFF >= 2,
%  then CUTOFF is considered as the maximum number of clusters to
%  keep in the hierarchical tree generated by LINKAGE. The output T is
%  a vector of size M containing a cluster number for each obrvation.
%
%  T = CLUSTERDATA(X,CUTOFF) is the same as
%      Y = pdist(X, 'euclid');
%      Z = linkage(Y, 'single');
%      T = cluster(Z, 'cutoff', CUTOFF);
%
%  T = CLUSTERDATA(X,'PARAM1',VAL1,'PARAM2',VAL2,...) provides more
