[Jprogramming] an inverse to oblique

[Pascal Jasmin]

More specific to what I want, based on looking at diagonal relationships within data, I wish to update a value in the original matrix, but I think the original question is easier more flexible.  I can't think of a better way than to generate indexes,

(< 0 0) ,&< (1 0 ; 0 1) ....

</. i.5 5
+-+---+------+---------+------------+----------+--------+-----+--+
|0|1 5|2 6 10|3 7 11 15|4 8 12 16 20|9 13 17 21|14 18 22|19 23|24|
+-+---+------+---------+------------+----------+--------+-----+--+

is there a way starting with the above boxes, to make the i. 5 5 table (without relying on magic within the data)
