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.

I'm not understanding why sort(x, 'descend') is not correct. On matlab works.

function y = rev(x)
y=sort(x,'descend');
