how to vectorize for loop in this section

Here's the code from a program.I try to vectorize this for loop,but I'm just a beginner in coding.Hope anyone who mastering Matlab can help.

 K = 5;
 M = 5;
 Y = [];
 g = [];

 for i=1:M       
    Y(i) = 1;
 end
 while Y(M)<K+1      
    for j=1:1:M-1   
        if Y(j)>K   
            Y(j) = 1;
            Y(j+1) = Y(j+1) + 1;
        else
            break; 
        end
    end
    Z = flip(Y,2);  
    g = [g;Z];
    sum = 0;
    for w=1:1:M
        if(w<=K)
            if(Z(w)==w)
                sum = sum +1;
                continue;
            else
                break;
            end
        else
            if(Z(w)==K)
                sum = sum + 1;
                continue;
            else
                break;
            end
        end
    end
    if(sum==M)
        break;
    end
    Y(1) = Y(1) + 1;  
 end

Refer this simple example to get your problem resolved.

A = [97 89 84; 95 82 92; 64 80 99;76 77 67;...
 88 59 74; 78 66 87; 55 93 85];

mA = mean(A);
B = zeros(size(A));
for n = 1:size(A,2)
    B(:,n) = A(:,n) - mA(n);
end
