Alex, I think you are not living up to your Technical Consultant II title.
This is the least you could have done to be considered an honest
effort:
from=:4 : 0
NB. indices-of-elements (IO=1) from y
NB. IO based indices of data to retrieve
indices=.x
NB. data array to be used
data_array=.y
NB. index origin
IO=.1
NB. calculate indices in J array that correspond to the indexed locations
standardized_indices=.indices-IO
NB. extract values from data array according to indices
result=.standardized_indices { data_array
result
NB. terminate the procedure
return.
)
(Anyone dares to improve on this code?)
