MATLAB: While loop for array. I want the loop stop when all element of “a” equal “b” but for this loop it will stop when only one element of a equal b. How could I fix it

arraywhile loop

I'd like to use while loop for array.

For example, I have the first array(a) ,10x10x10, and the second array(b),10x10x10 and this following is my condition:

while a ~= b …. a statement…..

end

I want this stop when all element of "a" equal "b" but for this loop it will stop when only one element of a equal b. How could I fix this statement?

Thank you very much

while not(isequal(a,b))

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.

Most efficient option is to create a matrix and store each output in a column

B = zeros(200, 10)
for i = 1:10
    % calculate A

    B(:, i) = A;
end

Another flexible alternative is to create a cell array.

B = cell(1,10);
for i = 1:10
    % calculate A
    B{i} = A;
end
