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, m, n, s] gives elements m through n in steps of s.

Take[list, , , ... ] gives a nested list in which elements specified by are taken at level i in list.

Take uses the standard sequence specification (see Section A.3.5).

Examples: Take[a,b,c,d,e, 3] .

Take[a,b,c,d,e, -2] .

Take[Range[15], 3, 12, 4] .

Take can be used on an object with any head, not necessarily List.

Take[list, , ] effectively extracts a submatrix from list.

Example: Take[a,b,c,d,e,f, -1, 2] .

Applying Take to a SparseArray object normally yields another SparseArray object.

See Section 1.8.4 and Section 2.4.2.
