It was about this: I needed to generate "all possibilities" for some combinations and each of those had a numeric property, say from 1 to 10000; I then had to count how many of the possibilities were of a given "category". So I created this array, generated all combinations, and incremented the matching slot each time.
it's histogram essentially? accumArray is doing so. internally, it's the same loop using STArray, but accumArray provide you pure API for such computations
And accumArray can also be used with UArray if laziness is a problem.
