MATLAB: Feature matching using Euclidean

euclideanImage Processing Toolbox

I am now doing copy move image forgery detection using DCT. Now I have some problem for matching part. It lagging for loading whole data since I am using looping to get the similarity between two row vector. Any idea to change my code in better way. Here is my code for the matching part.
z=0;
for num=1:group    
    for a=mS(num):mE(num)-1
        for b=a+1:mE(num)
            z=z+1;
            Dsimilar(z,1) = norm(sort(a,:)-sort(b,:))
        end
    end
end

That is not a valid calling form for the sort() function, so that code will not execute.
Why would you want to sort a single integer anyhow?
