using break and continue to using true extend ?

Hi guys,

I am trying to get input in the true interval such as that if m value interval 0<m<20 continue to process(jump to next row), but m>20 break the process with error message. How can ı do that with while or for and continue, break functions can anyone help me ?

Mass = input('please enter the mass');
 

while 0<Mass || Mass<20
    
   continue
end

while Mass>20
    
    break
    
    fprintf('the wrong extend of value'); 
end

I have tried that but doesn't process. Could you help me ?

What should happen for m <= 0 ? It should not continue to process, but it should also not generate an error message ?

It sounds like you want to check the conditions with if statements inside your while loop:

while true
    % do stuff
    Mass = input('please enter the mass');
    if Mass > 20
        break
        fprintf('the wrong extend of value'); 
    end
    % already checked Mass > 20
    if Mass > 0
        continue
    end
    % do stuff if Mass <=0
end
