element n only. { m, n } elements m through n inclusive. { m, n, s } elements m through n in steps of s. Drop can be used on an object with any head, not necessarily List. For a matrix, Drop [ list, seq 1, seq 2] effectively drops all elements except those in a submatrix of list. Drop works on SparseArray objects.

Chop [ expr, delta] replaces numbers smaller in absolute magnitude than delta by 0. Chop uses a default tolerance of 10 -10. Chop works on both Real and Complex numbers.

05.04.2017 · If you want to drop the first element from a list a the statement Drop [a,1] returns a list the same as a without its first element. Note that this does not update a. To do that you could assign the result to a, eg a = Drop [a,1]

StringDrop [ " string ", { m, n, s }] drops characters m through n in steps of s. StringDrop uses the standard Wolfram Language sequence specification. StringDrop [ BioSequence [ " type ", " seq "], spec] applies the operation to the string " seq " yielding a BioSequence result. Given a circular BioSequence and a starting position greater than ...

The Wolfram Data Drop is a general repository for data that is incrementally added, typically from external sources, through APIs as well as web, email, and other interfaces. Databin — symbolic representation of a Wolfram Data Drop databin. CreateDatabin — create a new databin, potentially specifying an interpretation to use.

Apr 08, 2011 · Mathematica 6 added TakeWhile, which has the syntax: TakeWhile [ list, crit ] gives elements ei from the beginning of list, continuing so long as crit [e i] is True. There is however no corresponding "DropWhile" function. One can construct DropWhile using LengthWhile and Drop, but it almost seems as though one is discouraged from using DropWhile.
