Subject: Another Basic Ruby Question

Within the Class I define things which I would expect to be Global.
Both the matrix and the reference to class are not seen in the method
calculate, as they fall outside of the method declaration.  How do I
make them visible, so they can remain where they are( Yes, I could pass
the matrix variable - e.g., calculate(m)- but is there another way to do
this?)  I don't think I could pass subr in this manner.

Class Subroutines

#some subroutines listed here
   def altitude(abs_psr_inhg)
      #stuff
   end

end


Class Ballistics

   require 'Matrix'

   m = Matrix[[1,2,3],[4,5,6]]
   subr = Subroutines.new

   def calculate

      puts m
      alt = subr.altitude(abs_psr_inhg)


   end

end
