BUILT-IN MATHEMATICA SYMBOL
Take
Take[list, n]
gives the first n elements of list.
Take[list, -n]
gives the last n elements of list.
Take[list, {m, n}]
gives elements m through n of list.
Take[list, seq1, seq2, ...]
gives a nested list in which elements specified by 
are taken at level i in list.
- Take uses the standard sequence specification:
-
| All | all elements |
| None | no elements |
| n | elements 1 through n |
| -n | last n elements |
| {n} | element n only |
| {m,n} | elements m through n inclusive |
| {m,n,s} | elements m through n in steps of s |
- Take can be used on an object with any head, not necessarily List.
- Take[list, seq1, seq2] effectively extracts a submatrix from list.
- Applying Take to a SparseArray object normally yields another SparseArray object.
Take the first 4 elements from a list:
| Out[1]= |  |
Take the last 3 elements:
| Out[1]= |  |
Take elements 2 through 4:
| Out[1]= |  |
