MATLAB: Reverse character array using recursion

recursion

I'm having trouble creating a function that would reverse a character array using recursion. For example, I want my function to return 'py' when inputting "yp". My overall code doesn't seem right though.
function array2 = charReversal(array1)
if array1==0
    return;
else
    array2=chsrReversal(reverse(array1,array1-1));
    disp(array2)
end

Best Answer

I assume this is homework so I'm hesitant even answering the question since the whole purpose of the exercise is to make you think of a recursive algorithm.
It is trivial to reverse a string by recursion: take the first element of the string, put it at the end of the string returned by calling the recursive function with the rest of the string (from character 2 to end). The recursion stops when the function receives only 1 character.
