Simple 2D Array Behavior in Ruby

ruby_2d_array.rb

#!/usr/bin/env ruby

#Scientific programming deals with arrays of numbers.  
#Here's a quick snippet showing how Ruby behaves with arrays.

strike_dip = [ [ 12.0, 30.0 ],
               [ 43.0, 12.0 ]]

puts "Whole array"
puts strike_dip

puts "First pair"
puts strike_dip[0]
puts "Second pair"
puts strike_dip[1]

strike_dip.each do | sd|
  print "Strike/dip: ", sd
  puts
end

=begin

This script outputs: 

Whole array
12.0
30.0
43.0
12.0
First pair
12.0
30.0
Second pair
43.0
12.0
Strike/dip: [12.0, 30.0]
Strike/dip: [43.0, 12.0]

Easy peasy.
