MATLAB: While-loop condition – arrays equal within a tolerance

isequalwhile loop

Hi guys!
I simplified the problem according to my issue. I basicly want to iterate arrays within a while function. But as soon as one element of the array is true, the while loop is not executed anymore. I want that the while looping is iterating until all elements of the arrays are euqal within a tolerance. 
A = [5,2,1,0,0];
B = [4,1,0,0,0];
for i = 1:5
 i = i+1
    while not(A-B < 0.1*ones(5,1)) & ...
        disp('Increase B')
     B = B + 0.01;
    end
end

Best Answer

for you case, I understand that you want the maximum absolute difference being below a limit?
In that case, the "stay in" condition is:
while max(abs(A-B), [], 'all') > you_limit
   ... 
end
the option on the max function is to ensure that you return 1 maximum whatever size have A and B.
