Enumeration of permutations


P = perms(v)


P = perms(v), where v is a row vector of length n, creates a matrix whose rows consist of all possible permutations of the n elements of v. The matrix P contains n! rows and n columns.

perms is only practical when n is less than about 11 (for n = 11, the output takes over 3 gigabytes).


perms([2 4 6])

ans =

   6   4   2
   6   2   4
   4   6   2
   4   2   6
   2   4   6
   2   6   4
