Coefficient of variation method matlab code [easy to understand]

Hello everyone , I meet you again , I'm your friend, Quan Jun .

function [ w,ave,score] = byxsf( A )
[m,n]=size(A);%m: Number of objects ,n： Number of indicators 
v=zeros(1,n);
w=zeros(1,n);
for i=1:n
    v(i)=std(A(:,i))/mean(A(:,i));
end
for i=1:n
   w(i)=v(i)/sum(v);
end
disp(' The weight of ：')
w

score=w(1)*A(:,1)+w(2)*A(:,2);% This part should be modified according to the actual situation 

disp(' Average score ：')
ave=mean(score)
end
