I think the test cases are not correct. Can you check this?

Sky Sartorius on 10 Oct 2013

The test cases expect isequal(NaN,NaN) to return true. This is wrong.

J.R.! Menzinger on 10 Oct 2013

please use the function "isquealn" http://www.mathworks.de/de/help/matlab/ref/isequaln.html

I went ahead and made the test suite change that José suggested above.

Clever! If the system doesn't work properly, work around it.

Alfonso Nieto-Castanon on 15 Oct 2013

Thanks :) in retrospect I probably should have overloaded isequal with isequalwithequalnans instead, but I guess this makes a similar point... (and if you are interested, the whole 'singularity' series of problems is devoted to "work arounds" for this sort of ill-defined testsuites)
