How to find the maximum element among the minimum elements in the columns in matrix m:n? With using loops.

It seemed simple from the beginning, but I got confused. Can anyone show a script that will do this?

% % so... I started like this:
n = input(num2str('Rows: ', 's'));
m = input(num2str('Columns ', 's'));
massive = round(100+(200-100)*rand(n,m));
disp(massive)
for i = 1:m
strr = massive(:,i);
for j = 1:n
% % And there should be a function that compares the elements, selects the minimum in the column and then compares which one is the maximum. I can't figure out what it should be.
end
end

There's never any need for a loop for things like that. Loops usually complicate the code in matlab.
maxofcolmin = max(min(massive, [], 2)); %return the maximum of the minimum across the columns of massive

Thank you! I know that all can be done shortly and simply. But the task requires the use of loops, and this is the problem.

Oh, it's some homework. I'm afraid you'll have to work it out yourself. It's not that hard. Keep track of your current minimum/maximum. Compare your element to that and if it is smaller/greater replace the current value.
