Check if a palindrome.

I have the script:

%1. Clear the memory and command window.

clear
clc

%2. Input a string.

string = input('What is your string: ', 's');

%3. Check if the string is a palindrome or not.

if string == fliplr(string);
  disp (['The string, ' string ', is a palindrome.'])
else
  disp (['The string, ' string ', is not a palindrome.'])
end

I want to make it so if the user enters anything but a word for the string it does not run and maybe instead of flipping the string comparing each cell. e.g if letter 1 is the same as the last letter, if letter 2 is the same as the second last letter. This method would be prefered. Also how would i make it so that that i could enter a cell array of striings and a vector of logical values was returned.

Looks almost identical to a question I answered a few days ago http://www.mathworks.com/matlabcentral/answers/123671#answer_131334. You need to cast to lower case and remove spaces. You can use inputdlg() to ask the user for several strings at a time and get a cell array.

sum=0;
n=input('Tell me a number \n');
count=input('no. of digits\n')
x=n;
if (count>=2)
    for i=1:n
        if (n>0)
            r=round(rem(n,10)-0.1);
            sum=sum*10+r;
            n=round((n/10)-0.1);
            c=x-sum;
        else
            break
        end
    end
    if (c==0)
        disp('the no. is palindrome');
    else
        disp('the no. is not palindrome');
    end
else
    disp('the no. is not palindrome');
end
