There should be a space between if keyword and the condition
if length(txt)<=1
%^ insert a space here
Apart from that, the logic is correct, but you just have a misplaced bracket. Following is correct
ok=(txt(1)==txt(end))&&palindrome(txt(2:end-1));

function ok=palindrome(txt)
if length(txt)<=1 % added space
ok = true;
else
ok = (txt(1)==txt(end)) && palindrome(txt(2:end-1));
% close parentheses --^
end
end

Editor's note: I added the comments here so that readers know the two lone characters that were actually changed.

function ans=palindrome(v)
if v(1)==v(end)
ans=true;
if length(v)==1 || length(v)==2
return
else
palindrome(v(2:length(v)-1));
end
else
ans=false;
end
end

function p = palindrome(n)
if length(n)/2<1
p = 2
else
p = n(1) == n(end)
p = [p palindrome(n(2:end-1))]
end
p = ~ismember(0,p)
