I am trying to write a recursive code to check whether a string is palindrome or not, when i am running a trial case a error message shows up stating "he function call palindrome('madam') caused an error and did not complete (MATLAB:TooManyOutputs)".

% I am writing a code to find the palindrome of a string using recursion but i am getting the error The function call palindrome('madam') caused an error and did not complete (MATLAB:TooManyOutputs)
function palindrome(v)
if length(v) <= 1
true
return;
end
if v(1) ~= v(end)
false
return;
end
palindrome(v(2:end-1));
end

Does your function actually return ANY output argument?
What happens when you just type false or true on the command line? Does that return anything? Or does it just dump something to the command window?
I think you need to do some reading about functions and how to use them.
When you write a function header, one thing you need to do is tell MATLAB what variables to return.

If you want to return an output argument then it must be declared in the function, e.g.:
function out = palindrome(v)
if length(v) <= 1
out = true;
return
end
if v(1) ~= v(end)
out = false;
return
end
out = palindrome(v(2:end-1));
end
You still have a few more bugs to fix...
