Details:

In Matlab the unique function now has a different syntax from Octave. Here is
the Matlab syntax:

C = unique(A)
C = unique(A,setOrder)
C = unique(A,occurrence)
C = unique(A,___,'rows')
C = unique(A,'rows',___)
[C,ia,ic] = unique(___)
[C,ia,ic] = unique(A,'legacy')
[C,ia,ic] = unique(A,'rows','legacy')
[C,ia,ic] = unique(A,occurrence,'legacy')
[C,ia,ic] = unique(A,'rows',occurrence,'legacy')


setOrder can be 'stable' to preserve the order or 'sorted' (the default.

occurance is 'first' or 'last' (already supported in Octave).
