Return a sequence of sequences:
|
2 |
=A1.(~2) |
Get the 2nd child member of each member sequence in A1’s sequence:
|
3 |
=A1.([~(1),~2]) |
Get the 1st and the 2nd child member of each member sequence in A1’s sequence:
|
4 |
=A1.groupc(~(3);[(~1),(~2)]) |
Group A1 by the 3rd child member of each member sequence, performs transposition on it and return the following result:
