I imagine you are going to need to use "isequalwithequalnans" in your testsuite instead of "isequal" for this problem

Now, I have changed the assert statement

Massimo Zanetti on 26 Oct 2016

Example is wrong. Input vector x must be

x = [1; 2; 3; 4; 5; 6]

not

x = [1; 2; 3; 4; 5; 6; 7; 8]

I believe in tests 3&4 you may be missing a 3 here and there?

Mehmet OZC on 1 Aug 2015

That's right, I have fixed it too
