Feature #5145

Function extension of Array#transpose

Added by Makoto Kishimoto about 4 years ago. Updated almost 3 years ago.



Currently, Array#transpose doesn't transpose iliffe vector that
size of arrays in array are not same.

But iff the sequence of size is monotone nonincreasing, there is
natural transposition.

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

Attachment is monkey patch implementation by Ruby .
