Raze: Difference between revisions

:''The symbol <source lang=apl inline>⊃</source> is more commonly used for [[First]] or [[Mix]].''

{{Built-in|Raze|⊃}}, <source lang=j inline>;</source> in [[J]], or '''Join''' (<source inline>∾</source>) in [[BQN]], is a [[monadic function]] which combines [[element]] arrays of a [[nested]] [[vector]] along the first [[axis]] (in accordance with [[leading axis theory]]). Thus, the [[major cell]]s of the Raze of an array are the major cells of its element arrays: unlike [[Mix]], which removes a level of [[depth]] while keeping outer and inner axes separate, Raze merges the outer vector's axis with the first axis of each element. Raze is present in [[A+]], [[J]], and [[BQN]].
