% I want to create a loop for all number combination from 1 to 10^4 for a^3+b^3=c^3
% My Script does not work. There is no Output and no errror code.
% When i change i to 2 then it works but why not when i use 3 for i
% Please help me to fix my problem
% Thank you
n = 10^4;
i = 3;
for a = 1:n
   for b = 1:n
        for c = 1:n
            if (((a^i)+(b^i)) == (c^i))
                result = ['Bingo ' 'For a: ' num2str(a) ' For b: ' num2str(b)  ' For c: ' num2str(c)];
                disp(result)               
                
        end
    end
end
end

You could could potentially display 1.000000000000000e+12 values. I would seriously reconsider doing that.

The reason nothing is displayed is because none of the values tested meet the condition of your if statement. In fact, the only integer solution to this equation is a=b=c=0 (proved by Fermat and perhaps Euler).

So @Cris LaPierre if i use n=10^4 instead n=2 is it right like that for my task?

n=10^4; 
i=3; 
for a = 0:n 
    for b = 0:n 
        for c = 0:n 
            if a^i+b^i == c^i 
                result = ['Bingo ' 'For a: ' num2str(a) ' For b: ' num2str(b)  ' For c: ' num2str(c)]; disp(result)                
            end 
        end 
    end 
end

@Cris LaPierre now i think i understand my task. i already created my script which is right for the task. he does not want any solution only the script.
