一个简单的贝叶斯分类器

function plotdata(test,testclass)
[m,n]=size(test);
for(i=1:m)
    if(testclass(i,:)==[1,0,0])
       h=plot(test(i,1),test(i,2),'LineWidth',1,'Marker','x','Color','r');
       hold on
     end
     if(testclass(i,:)==[0,1,0])
       h=plot(test(i,1),test(i,2),'LineWidth',1,'Marker','o','Color','b'); 
       hold on
     end
     if(testclass(i,:)==[0,0,1])
       h=plot(test(i,1),test(i,2),'LineWidth',1,'Marker','*','Color','k'); 
       hold on 
      end
