perms

All 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
       4     6     2
       6     2     4
       2     6     4
       4     2     6
       2     4     6
