Octave has a limited set of functions for managing sets of data, where a set is defined as a collection unique elements.

— Function File: **create_set** (`x`)

Return a row vector containing the unique values in

x, sorted in ascending order. For example,create_set ([ 1, 2; 3, 4; 4, 2 ]) => [ 1, 2, 3, 4 ]

— Function File: **union** (`x, y`)

Return the set of elements that are in either of the sets

xandy. For example,union ([ 1, 2, 4 ], [ 2, 3, 5 ]) => [ 1, 2, 3, 4, 5 ]
