获得3个和4个聚类中心然后进行比较，先用fcm函数进行聚类，聚类成3个和4个类别再进行比较分析(matlab fcm)

Do you still use GINPUT to graphically select points on current axes with the mouse? Try this one! With GINPUT2 you can also: 1. ZOOM: in, out (double-click)! 2. PAN: when dragging! 3. DELETE: last selected point! 4. PLOT: while selecting! (optional, just input the line style!) 5. SCALE or GEOREFERENCE images! (optional, just input: true) So, besides of selecting points in a more precise way (zooming) you can DIGITIZE(!!!) lines with the last two options, by simply using: >> ginput2(true, .k ) Enjoy it!
