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
