Solution 1

A quick google search i found this,

Transform number into string:
num2str(123)

Use fliplr:
fliplr(num2str(123))

Solution 2

at least this one worked:

C#

function rev = reverse(num)
rev=0;
while(num>1)
    m= mod(num,10);
    rev = floor(rev * 10 + m);
    num = num /10;
    %-----display situation each turn
    disp(num);
end
end
