%Data
xm(:,:,1)= [1 2 3 4;2 3 4 5;3 4 5 6;4 5 6 7 ];
xm(:,:,2)= [2 3 4 5;3 4 5 6;4 5 6 7;5 6 7 8];
n=size(xm,3);
%Loop Method
for i=1:size(xm,1);
for j=1:size(xm,2);
cf1(i,j)=(abs (sum(xm(i,j,:))).^2) / (n* sum(abs(xm(i,j,:).^2)));
end
end

%Vectorized method
cf2 = abs(sum(xm,3).^2)./(n*sum(abs(xm.^2),3))
