I think this ambiguity, or one like it, is what kicked off another, very long, discussion in another thread: all of these are arrays.
I've always used "multi-dimensional arrays" to refer to arrays with rank of three or more. Though this is also ambiguous, people seem to know what I'm talking about. Another possibility is "tensor" but I see that the two top definitions Bing gives me don't quite agree: Wikipedia mixes what J calls nouns and verbs whereas the Wolfram Mathworld definition mirrors the general term "array" as J uses it. Maybe it just varies according to your audience.
