I haven't read the rest of this thread, but to respond to this bit:
Since \ is an adverb, you are not restricted to <\ . You may use any
(monadic) verb in place of < .
Also, \ will work on arrays of rank > 1. However, it will treat any such
array as a list of items (of arbitrary rank), i.e. its frame has length 1.
If you want arbitrary frames, you can use ;.3 (or _3 ). For example:
3 3 <;._3 i. 4 4
+--------+--------+
|0 1 2 |1 2 3 |
|4 5 6 |5 6 7 |
|8 9 10 |9 10 11 |
+--------+--------+
| 4 5 6| 5 6 7|
| 8 9 10| 9 10 11|
|12 13 14|13 14 15|
+--------+--------+
Does that help at all?
