Determine whether the vector is symmetric or not (vector could be even or odd in length).
For example:
x = [1 2 3 3 2 1] is symmetric
x = [1 2 3 4 3 2 1] is symmetric as well!
x = [-1 -2 -3 3 2 1] is not symmetric

Case #3 is not symmetric...please check.
I fixed the wording.
Why the vector from "Test Suite" "Test 3" is symmetric?
x = [-1 0 0 1];
y_correct = 1; %% WHY 1?
I updated test case #3.
Hello everyone,
just a quick hint for this test: at the moment, one can pass this test simply checking whether x(1)==x(end).
However, to me at least, it makes more sense to split the check for even and odd vectors and to check if the corresponding symmetrical elements are the same or not.
If any of the pairs of elements are not equal, then we exit the cycle and we terminate with a false/0.
This is the way I figured out a robust check, otherwise it's just cheating.
KR, Andrea
