LDA是人脸识别中比较基础的一个算法

function rate=testing(TestX,ClassNum,EachTestClassNum,TestClass,A,MeanEachClass)

for i=1:ClassNum
    TrainPro(:,i)=A'*MeanEachClass(:,i);
end

N=EachTestClassNum*ClassNum;
T=0;
for i=1:N
    TestPro=A'*TestX(:,i);
    Eudistance=inf;
    for j=1:ClassNum
        %distance=norm(TestPro-B(:,(j-1)*p+1:j*p));
        distance=norm(TestPro-TrainPro(:,j),'fro');%%%%%%%%%%
        if distance<Eudistance
            Eudistance=distance;
            testclass(i)=j;
        end
    end
    if testclass(i)==TestClass(i)
        T=T+1;
    end
end
rate=T/N;
clear('p','N')
