- Join[List 1, List 2, ...]
- Joins the two (or more) lists.
- Note: The new list contains all elements of the initial lists even if they are the same. The elements of the new list are not re-ordered.
- Example:
Join[{5, 4, 3}, {1, 2, 3}]creates the list {5, 4, 3, 1, 2, 3}.
- Join[List of lists]
- Joins the sub-lists into one longer list.
- Note: The new list contains all elements of the initial lists even if they are the same. The elements of the new list are not re-ordered.
- Example:
Join[{{1, 2}}]creates the list {1, 2}.Join[{{1, 2, 3}, {3, 4}, {8, 7}}]creates the list {1, 2, 3, 3, 4, 8, 7}.
