Arrays in Ruby don't have a static length, you can append to them at will...

irb(main):001:0> anArry = Array.new
=> []
irb(main):002:0> anArry << Array.new
=> [[]]
irb(main):003:0> anArry << Array.new
=> [[], []]
irb(main):004:0> anArry[0][0] = 1
=> 1
irb(main):005:0> anArry
=> [[1], []]
irb(main):006:0> anArry[0][1] = 2
=> 2
irb(main):007:0> anArry
=> [[1, 2], []]
irb(main):008:0> anArry[1][0] = 3
=> 3
irb(main):009:0> anArry[1][1] = 4
=> 4
irb(main):010:0> anArry
=> [[1, 2], [3, 4]]
