perms - Enumeration of permutations

Syntax

P = perms(v)

Description

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 8 or 9.

Example

perms([2 4 6])

ans =

   6   4   2
   6   2   4
   4   6   2
