Let me start by saying I am completely new to Mathematica, and I just installed version 9 about an hour ago. So apologies in advance if I'm doing something silly here!
I am trying to run a Mathematica notebook found here: http://mathworld.wolfram.com/notebooks/PointLattices/Polyomino.nb
Apparently I need the Mathworld packages available in the zip file here, particularly polyomino.m
I have unzipped the add ons and put them in a MathWorld folder as instructed. I put this in a few different places that should be accessible to Mathematica.
However, when I try to run the notebook, I consistently get:
(Debug) In:= <<MathWorld`Polyomino`
(Debug) During evaluation of In:= Get::noopen: Cannot open MathWorld`Polyomino`. >>
(Debug) Out= $Failed
I don't know if Mathematica can't find the file, or if there is a problem with the code. I think they were created for Mathematica 6.0, so maybe they are no longer compatible.
Would any kind soul take a look at this and see if they can get this Polyomino.nb to work on Mathematica 9.0? Maybe I am not doing something very basic correctly.
Thank you in advance
