transpose

Transpose

{{{1}}}

Transpose (a.k.a. flip) swaps the leading two axes of a 2+ dimensional rectangular array. Dialects differ in their treatment of atoms, lists, and ragged arrays.

 +("ab";"cd";"ef")
("ace"
 "bdf")

 +(`a`b`c;`d)
(`a`d
 `b`d
 `c`d)

Atoms and lists

Transposing a list in oK or ngn/k enlists it. Transposing an atom enlists twice:

 +,0
,,0
 +0
,,0

K4 and Kona return the argument as-is.

K9 throws a rank error.
