The transpose of a matrix could also be achieved if Monadic Transpose had [[rotate]]d the axes, rather than reversed them, but the design was chosen so keep the matrix identity <syntaxhighlight lang=apl inline>(m+.×n) ≡ ⍉(⍉n)+.×⍉m</syntaxhighlight> or <syntaxhighlight lang=apl inline>(m+.×n) ≡ n+.×⍢⍉m</syntaxhighlight> for [[array]]s of all [[rank]]s.<ref>[[Adin Falkoff|Falkoff, Adin]] and [[Ken Iverson]].
