I understand that Matlab has inbult functions for finding maximum and minimum, however I am trying to learn how physically learn these skills, for instance how would i go about using for loops that will search for the maximum/largest number while testing if the new value is more than the current value in an array i made called RandomNumber... But i don't know how to go about utilising the for loop in this manner, would someone update me on this using my code thank you.

%% My current understanding of the possible script

RandomNumbers = [3, 9, 27, 81, 7, 9, 10, 33, 2, 55];

LargestNumber [];

for x = 1:10

LargestNumber = ?

end

disp(['The largest number is ',num2str(LargestNumber),])

在 MATLAB Online 中打开

RandomNumbers = [3, 9, 27, 81, 7, 9, 10, 33, 2, 55];
LargestNumber = RandomNumbers(1);
for i = 2:length(RandomNumbers)
if  RandomNumbers(i) > LargestNumber
    LargestNumber = RandomNumbers(i) ; 
end
end
fprintf('The largest number is %f\n',LargestNumber)
The largest number is 81.000000
