Unless something has changed in the newest version of MATLAB, isequal doesn't work with NaNs.

Nan will be studied in the UICBioE240 9.79. Be patient...

I think test suite should use assert(isequalwithequalnans(y,y_correct))

isequal(NaN,NaN)
ans = 0

isequaln(NaN,NaN)
ans = 1

Test suite has been fixed and additional cases are added.
