Details:


>> test unique
***** assert (unique ([1,NaN,Inf,NaN,Inf]), [1,Inf,NaN,NaN])
!!!!! test failed
ASSERT errors for:  assert (unique ([1, NaN, Inf, NaN, Inf]),[1, Inf, NaN,
NaN])

  Location  |  Observed  |  Expected  |  Reason
     .          O(1x5)       E(1x4)      Dimensions don't match
>> unique ([1,NaN,Inf,NaN,Inf])
ans =
     1   NaN   Inf   NaN   Inf


6.4.0 does it differently:

>> unique ([1,NaN,Inf,NaN,Inf])
ans =
     1   Inf   NaN   NaN


I'm still surprised by the double NaN - is that intended bug-for-bug Matlab
compatibility? :-)  I saw that Matlab r2020b also returns double NaN's.
