I have to use a while loop to ensure user input is an integer between 3 and 50. I set up constraints to do this but once I use the rem function to flag for noninteger it runs and infinite loop for my fprintf. What am I doing wrong?
%get user input
prompt = ('Enter a number for the length of your array: ');
x = input(prompt);
%have user input be an integer between 3-50
%test for noninteger
while (x < 3 || x > 50 || rem(x,1) ~= 0)
fprintf('Please enter an integer between 3 and 50: ');
end

You do give a chance for the user to enter x again, so you are testing the same x each time.
