I have a problem similar to the one shown below. Both the verbs g and h depend on calculating f first so this seems like an inefficient way of doing it where f produces only nonnegative integers from its argument. Is there a better approach?
g=:,:f h=:*@f f=: 3&| NB. not the real f, but f is more compute heavy 3 : '(h y)}g y' i.10 NB. an example calculation 0 1 2 3 1 2 6 1 2 9 ]`h`g } i. 10 NB. another "tacit" calculation 0 1 2 3 1 2 6 1 2 9 -- (B=) <-----my sig Brian Schott ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
