| 8828 | 22 Octave has a limited number of functions for managing sets of data, where a |
| 7001 | 23 set is defined as a collection of unique elements. In Octave a set is |
| 6741 | 24 represented as a vector of numbers. |

37 Octave also supports the @emph{Exclusive Or} set operation, and |
| 6741 | 38 membership determination. The functions for set operations all work in |
| 39 pretty much the same way. As an example, assume that @code{x} and | |
| 40 @code{y} contains two sets, then | |
| 41 | |
| 42 @example | |
| 43 union(x, y) | |
| 44 @end example | |
| 45 | |
| 46 @noindent | |
| 47 computes the union of the two sets. | |
