- Unique[ <List L> ]
- Returns list of elements of list L in ascending order, repetitive elements are included only once. Works for both a list of numbers and a list of text. See also the Frequency command.
- Example:
Unique[{1, 2, 4, 1, 4}]yields "{1, 2, 4}".Unique[{"a", "b", "Hello", "Hello"}]yields {"'Hello", "a", "b"}.
CAS Syntax
- Unique[ <List L> ]
- Returns a list where each element of L occurs only once.
- Example:
Unique[{1, x, x, 1, a}]yields {1, x, a}.
