Hi, Suppose I have a list of arrays, say g = {a, b, c} where a, b, and c are arrays, and I would like to calculate Outer[Times, a, b, c] how do I do it? I tried Apply[Outer[Times,#]&, g], as in Apply[Outer[Times, #] &, {{1}, {1}}], but that does not yield the right answer. So the question is: how does one convert a list {a, b, c} into arguments to a function of variable number of arguments? Thanks! An auxiliary question: within the function f[x__] := ... what kind of object is x? It's not a list, but what is it? Many thanks in advance, Sam
