Write a script that prompts the user for a string, error-checking until the user enters something (the error would occur if the user just hits the Enter key without any other characters first). The script then prints the length of the string.

This blurb of code is written to accept a string as an input. If you don't want it to accept only a string then you can get rid of the ,'s' portion. Enjoy :).
str = input('Plese enter your value: ','s');
while isempty(str)~=0
str = input('Plese enter a valid value: ','s');
end
