averagem.m

用matlab实现的算法

function preprocess=averageM(Matrix)
[row,column]=size(Matrix);
Matrixsum=sum(Matrix);
Matrixaver=zeros(1,column);
for ii=1:column
    number=0;
    for jj=1:row
        if Matrix(jj,ii)~=0 
            number=number+1;
        end
    end
    Matrixaver(1,ii)=Matrixsum(1,ii)/number;
end
preprocess=zeros(row,column);
for i=1:row
    for j=1:column
        preprocess(i,j)=Matrix(i,j)*100/Matrixaver(1,j);
    end
end
