- Last[ <List> ]
- Gives a new list that contains the last element of the initial list.
- Example:
Last[{1, 4, 3}]yields {3}.
- Note: To get the last element use
Element[{1, 4, 3}, 3]. - Last[ <List>, <Number of elements> ]
- Gives a new list that contains just the last n elements of the initial list.
- Example:
Last[{1, 4, 3}, 2]yields {4, 3}.
- Last[ <Text> ]
- Gives last character of the text.
- Example:
Last["Hello"]yields "o".
- Last[ <Text> , <Number of elements> ]
- Gives the last n characters of the text.
- Example:
Last["Hello",2]yields "lo".
CAS Syntax
- Last[ <List> ]
- Gives a new list that contains the last element of the initial list.
- Example:
Last[{1, 4, 3}]yields {3}.
- Note: To get the last element use
Element[{1, 4, 3}, 3]. - Last[ <List>, <Number of elements> ]
- Gives a new list that contains just the last n elements of the initial list.
- Example:
Last[{1, 4, 3}, 2]yields {4, 3}.
Note:
See also First Command.
