be to use modules in Ruby and star= t from there.

The first.rb from Jake's example could be

module Statistics
=C2=A0 def correlation(a,b)
=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0 # code for correlation
=C2=A0 end

=C2=A0 def stddev(a)<= br>=C2=A0=C2=A0=C2=A0=C2=A0 # code for standard deviation
=C2=A0 end
= end

In second.rb, you could do
=C2=A0 require "./first"=
=C2=A0 include Statistics=C2=A0 # similar to USE in fortran
=C2=A0=C2=A0=
=C2=A0a=3D[1,2,3,4]
=C2=A0b=3D[0,0,0,0]

=C2=A0correlation(a,= b)
=C2=A0stddev(a)

hi Thomas,

=C2=A0you can use `require` to include any files that you want.

=C2=A0try this - in the same directory, create two files: `first.rb` and `second.rb`

`first.rb` could look like this:

Class Traveller
=C2=A0def initialize
=C2=A0 =C2=A0puts "I'm from the first.rb!"
=C2=A0end
end

=C2=A0...and `second.rb` like this:

require './first.rb'
# note: require 'first' will usually also work

Traveller.new

=C2=A0do a search for `ruby require` or `ruby require_relative`, and you&#= 39;ll
find more info...

=C2=A0hth-

=C2=A0- j
