perms (MATLAB Functions)

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:

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

Limitations

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