search for it first,

$ qri transpose

------------------------------------------------------ Multiple choices:

     Array#transpose, Matrix#transpose


so eg,

=> Matrix[[1, 3, 5], [2, 4, 6]]
>>  Matrix[[1,2,3,4], [1,2,3], [1,2]]. transpose
=> Matrix[[1, 1, 1], [2, 2, 2], [3, 3, nil], [4, nil, nil]]
