Kadar,

I was looking through my computers ruby packages and found one:

  libnarray-ruby1.9.1

claiming it:

  has numerical n-dimensional array class

Googling found:

  https://github.com/princelab/narray/wiki/Tentative-NArray-Tutorial

So, I tried it and, it works:

/home/evansl/prog_dev/ruby $ irb1.9.1
irb(main):001:0> require 'narray'
=> true
irb(main):002:0> a = NArray.int(2,3,4)
=> NArray.int(2,3,4):
[ [ [ 0, 0 ],
    [ 0, 0 ],
    [ 0, 0 ] ],
  [ [ 0, 0 ],
    [ 0, 0 ],
    [ 0, 0 ] ],
  [ [ 0, 0 ],
    [ 0, 0 ],
    [ 0, 0 ] ],
  [ [ 0, 0 ],
 ...
irb(main):003:0>

HTH.
