Take: Difference between revisions

{{Built-in|Take|↑}} is a [[Primitive function|primitive]] [[dyadic function]] which shortens or extends the right [[argument]] array along one or more [[Axis|axes]]. The [[vector]] left argument indicates the lengths of result axes, with a sign to denote whether [[element]]s should be taken starting from the beginning or end of each axis. Take was introduced in [[APL\360]] with the requirement that the left argument length match the right argument rank, and was extended in [[SHARP APL]] 19.0 to allow short left arguments. It is closely related to [[Drop]], which removes the parts of each axis that Take would include.
