With no [[function axis]], Enclose returns a [[scalar]] array whose only [[element]] is the argument. In the [[flat array model]] this means that the argument is placed in a [[box]], and the result is this box as a scalar. In the [[nested array model]] it can simply be viewed as creating a new array. However, if the argument is a [[simple scalar]], then the result will match the argument because nested array theory dicatates that simple scalars [[float]]. | |||
