y = [x(1),x(end)];
very easy like it!
Well, I guess my understanding that string is defined using (" " , i.e. double quotations) is incorrect. I thought class string was formally distinguished from char (defined using ' ', i.e. single quotes). I should have looked at the test-suite.
Yes, the title should be "Return the first and last character of a char array"
out = x([1 end])
This is legal even if length(x) == 1, because in that case, x(1) == x(end)
that is it
