I can't see the post in my browser, but Tom Dowling helpfully emailed
to say that on his Mac (non-Intel) running Mathematica 7.0.0 the code
above ran fine!
I'm using 7.0.1 on a windows (32 bit) platform, OS XP Pro SP3. Just to
check I'm not deluding myself, I ran an abbreviated version of the
steps above again. Here's the inputs & outputs shown:
In[1]:= << "Combinatorica`"
In[2]:= Edges[Cycle[3, Type -> Directed]]
Out[2]= {{1, 2}, {2, 3}, {3, 1}}
In[3]:= Edges[FromAdjacencyMatrix[
ToAdjacencyMatrix[Cycle[3, Type -> Directed], Type -> Directed],
Type -> Directed]]
Out[3]= {{1, 2}, {2, 3}, {1, 3}}
Is it just my system or can anyone else reproduce this?
Best regards
Andrew
