As a side effect of the thread 'Turning 0 into _1 1 in a list' there is
the question of reducing rank or should I say 'flattening' array's.
Iterative one for reducing arbitrary rank to a defined lower rank:
rank flatI array
2(,/@])^:(<[EMAIL PROTECTED])^:_ i.2 2 3 3
0 1 2
3 4 5
6 7 8
9 10 11
12 13 14
15 16 17
18 19 20
21 22 23
24 25 26
27 28 29
30 31 32
33 34 35
don't touch:
2(,/@])^:(<[EMAIL PROTECTED])^:_ i.3
0 1 2
non-iterative to rank 2
flat22 array
((*/@}:,{:)@$$,)i.2 2 3 3
0 1 2
3 4 5
6 7 8
9 10 11
12 13 14
15 16 17
18 19 20
21 22 23
24 25 26
27 28 29
30 31 32
33 34 35
don't touch
((*/@}:,{:)@$$,)i. 3
0 1 2
Is this the right way to handle this?
