You can also define it to have that rank by default:
asd =: 3 : 0 "0
t =. 2*(1+y)
1+t*(t-1)+i.4
)
asd 1 2 3
13 17 21 25
31 37 43 49
57 65 73 81
If you want all the numbers in one list rather than three lines then do:
,@:asd 1 2 3

I was searching in vain for many days how to specify rank to the verb,
defined in multiline manner. I've searched both through JforC and LJ
books; I was convinced that in-line setting of the rank is only possible
for on-line definitions. I've never seen even a hint to this.
Thank you very much, Matthew. Henry Rich, please, please, include this
bit of information explicitly into the next revision of your great book.
Yes, I'm newbie, and yes, I don't fully understand the logic of verb
definitions, or I could've tried to guess that myself, but it's still a
pity I was in the dark for so long regarding this matter.
