MATLAB Function Reference

perms

All possible 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. Matrix P contains n! rows and n columns.

Examples

The command perms(2:2:6) returns all the permutations of the numbers 2, 4, and 6:

• 2     4     6
  2     6     4
  4     2     6
  4     6     2
  6     4     2
  6     2     4
  

Limitations

This function is only practical for situations where n is less than about 15.
