i want to get an error if the user enters an input other than 1 to 16. even negative and zero should give error

while element > 16
      disp 'Error you entered a a number greater than 16. Please enter again!'
      element =input(prompt);
end

while true
  element = input(prompt);
  if ismember(element, 1:16); break; end
end

Why ugly while loop in this case?

this is working all right thank you for your help but if i could get a little message for displaying error as well i would be thankful to you

[Walter Roberson]

while true
  element = input(prompt);
  if ismember(element, 1:16); break; end
  disp('You need to enter an integer in the range 1 to 16')
end

"Why ugly while loop in this case?"

Situations like this almost always want to keep prompting until valid input is entered.
