BUILT-IN MATHEMATICA SYMBOL

Take

gives the first n elements of list.

Take

gives the last n elements of list.

Take

gives elements m through n of list.

Take

gives a nested list in which elements specified by

are taken at level i in list.

MORE INFORMATION

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 effectively extracts a submatrix from list.

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

Basic Examples (3)

Take the first 4 elements from a list:

Take the last 3 elements:

Take elements 2 through 4:

Take the first 4 elements from a list:

In[1]:=

Out[1]=

Take the last 3 elements:

In[1]:=

Out[1]=

Take elements 2 through 4:

In[1]:=

Out[1]=

Scope (7)

Take elements from the second to the second-to-last:

Take every other element:

Take the first two rows of a matrix:

Take all rows, and the first two columns:

Take the first two rows, and the last column:

Take a submatrix:

Take every other row and column:

Generalizations & Extensions (2)

Take works with any head, not just List:

Take works with SparseArray objects:

Applications (2)

Pick out a subimage:

Sample every third cell in an image:

Properties & Relations (5)

Take and Drop are complementary:

Take is often equivalent to Part extraction with Range:

Take is equivalent to Part extraction with Span:

Take gives an array whose first dimensions are its arguments:

Reverse[e] is equivalent to Take

Possible Issues (1)

Take always returns a list, even if it is just taking a single element:
