Take

Usage

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.


Notes

Take uses the standard sequence specification (see Section A.3.5).
• Examples: Take[ a,b,c,d,e , 3]LongRightArrow .
Take[ a,b,c,d,e , -2]LongRightArrow .
Take[Range[15],  3, 12, 4 ]LongRightArrow .
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]LongRightArrow .
• Applying Take to a SparseArray object normally yields another SparseArray object.
• Related package: LinearAlgebra`MatrixManipulation`.
