What does %#ok<SAGROW> comment mean in MATLAB?
I've encountered many MATLAB codes which have a `%#ok<SAGROW>` comments. This comment is used  in different circumstances and I can't figure it out what it means.

As an example:


    i = 1; 
    flag = true;
    for l = 1:k
        while(flag==true)
            if(probs(i)~=0)
                leaves(l).val = i-1; %#ok<*SAGROW>
                leaves(l).zero = '';
                leaves(l).one = '';
                leaves(l).prob = probs(i);
                i = i + 1; 
                flag = false;
            else
                i = i+1;
                flag = true;
            end
        end
    flag =true;
    end
