You'd have to write a wrapper that implements an array of triples as a triple of arrays. This isn't too hard. There's a new library in the works that should make this a lot easier -- Don abhay.parvate:
As far as I know, you can't. It needs machine representable types, such as Int, Double, Char, etc. But making a tuple of three UArray Int Double may help.

Thanks for help. I did some tests with UArray and it does the trick. The problem remaining is, how to implement UArray Int (Double, Double, Double)? UArray source code is far too cryptic for me.

it's boxed array which means that its elements are stored as thunks computed only when you actually use them. try UArray instead:
