Similar functionality can be obtained using unique(perms(V),'rows'), but this will create a possibly large intermediate array with N! rows. When V has J unique elements, each of which is repeated Kj times (j=1:J), then the number of unique permutations is N!/(K1!*..*KJ!) Cite ...

A matrix T that may be brought (by permutation of the rows and columns) in the form (199), with TA reducible is called incompletely reducible [van Kampen, 1981, p. 108]. Further, a stochastic matrix is called irreducible if it is neither completely or incompletely reducible. An alternative...

This is a weird one I noticed while calling unique(a, axis=0) for a 2D array a. If some values in the first column of a are <= 255 and others are >255, the output is incorrectly sorted. Maybe something somewhere is making an assumption a...
