Subject: Re: 2 dimentional array in ruby - niewbie


How about an OO solution:

class MultTable
  attr_reader :dim_x, :dim_y

  def initialize(dim_x, dim_y)
    @dim_x, @dim_y = dim_x, dim_y
  end

  def [](x,y); x*y; end

  def row(x)
    a=[]
    dim_y.times{|y| a << self[x,y]}
    a
  end

  def col(y)
    a=[]
    dim_x.times{|x| a << self[x,y]}
    a
  end
end

mt = MultTable.new(10, 10)

mt.dim_x.times do |x|
  p mt.row(x)
end

Cheers
