how can I find the max value out of iterative for loop ?

here, the problem is when, for loop iterate itself let's say 5 times, the first maxvalue from is 9, the second is 3, the third is 5, the fourth is 7 and the fifth is 3, so the max_maxvalue (global max) must be 9 out of these five iterations. But I got 3 as max_maxvalue (global max) which means its chose the max value from the last iteration NOT saving the previous max values and compare among them according to what I want.

Thanks in advance for any help

count=1;
while 1
    for i=1:20
        x(i)= % calculations
    end
    
    maxvalue(count) = max(x);
    count=count+1;
    
    if x(end) == maxvalue(end)
        break
    end
end
max_maxvalue=max(maxvalue);

Seems to be working:

count=1;
while 1
    for i=1:20
        x(i)= randi(87);% calculations
    end
    
    maxvalue(count) = max(x);
    count=count+1;
    
    if x(end) == maxvalue(end)
        break
    end
end

maxvalue

maxvalue = 1×3

86 86 77

max_maxvalue=max(maxvalue)

max_maxvalue = 86

first thank you for your response, but in first round from 1: 20, we can get the max for example 86, but when the for loop iterate again from 1: 20 we get the max value 77, now If I want to stop the code, so here the code consider 77 is the max value NOT consider 86 as the maximum value this is what I want to obtain it which is for example should consider 86 as max value

But as you can see in my RUN above, we did get a max_maxvalue of 86, as you desired.
