My apologies also -- I finally noticed that your
followup had this definition.
Anyways, here's a workalike for interp which
caches preserves intermediate results:
interp2=: 2 :'((i.1+m) ! ]) +/ .* ({. (1+m) difftb n)"_'
3 interp2 data "0 i. 10
0 1 8 27 64 125 216 343 512 729
and here is a slightly cleaner variation:
interp3=: 2 :'((i.1+m)&!"0) +/ .* ({. (1+m) difftb n)"_'
3 interp3 data i. 10
0 1 8 27 64 125 216 343 512 729
Note also, if you wanted to convert
(y !~ i. >: m)
to tacit form and were not comfortable with
writing tacit expressions, you could try something
like
13 :'y !~ i. >: 100'
and inspect its result for clues.
FYI,
