Added some more tests.
Test set needs a column vector.
As far as timing goes ...
x=rand(100,1);
tic;y=flipud(x);toc
Elapsed time is 0.068947 seconds.
tic;y=x(end:-1:1);toc
Elapsed time is 0.000026 seconds.

thanks Kristin but I got it on my own
I'm not understanding why sort(x, 'descend') is not correct. On matlab works.
GOOD
function y = rev(x)
y=sort(x,'descend');
end
i'm doing like this but i have 1 assertion error ? what's wrong?
"Iterate through the array from the last element to the first, decrementing the index by 1 in each iteration."
