Drop
Drop[
list
,
n
] gives list with its first n elements dropped. Drop[
list
,
-
n
] gives list with its last n elements dropped. Drop[
list
,
n
] gives list with its n
element dropped. Drop[
list
,
m
,
n
] gives list with elements m through n dropped. Drop[
list
,
m
,
n
,
s
] gives list with elements m through n in steps of s dropped. Drop[
list
,
,
, ... ] gives a nested list in which elements specified by have been dropped at level i in list.
Drop uses the standard sequence specification (see Section A.3.5). Examples: Drop[
a,b,c,d,e
, 2]
. Drop[
a,b,c,d,e
, -3]
. Drop[Range[7],
2, 5, 2
]
. Drop can be used on an object with any head, not necessarily List. Drop[
list
,
,
] effectively drops all elements except those in a submatrix of list. Example: Drop[
a,b,c
,
d,e,f
, 1, -1]
. See The Mathematica Book on the web:Section 1.8.4. See also: Rest, Take, Cases.
