MATLAB: Hi everyone, I have been trying to debug this for loop as it always retain the last value of the array even if none of the conditions meet for every element. For instance, using readings = [1 20 55 90], it will print that reading(4)>100.

breakfor loop

for ii = 1:length(readings)
    if readings(ii) > 100 
        break;
    end
end
fprintf('First reading above 100 is at index %d.\n', ii);

Best Answer

Try:
ix = 0;
for ii = 1:length(readings)
   
    if readings(ii) > 100
        ix = ii;
        break;
    end
    
end
fprintf('First reading above 100 is at index %d.\n', ix);
