Hi,
I'm looking for help trying to build a graph object in Mathematica, but getting the following error message:
a={{0,1,1,0,0,0,1,0,0},{1,0,1,0,1,0,0,1,0},{1,1,0,0,0,1,0,0,1},{0,0,0,0,0,1,0,0,0},{0,1,0,0,0,1,0,1,0},{0,0,1,1,1,0,0,0,1},{1,0,0,0,0,0,0,1,1},{0,1,0,0,1,0,1,0,1},{0,0,1,0,0,1,1,1,0}}
Out[52]= {{0,1,1,0,0,0,1,0,0},{1,0,1,0,1,0,0,1,0},{1,1,0,0,0,1,0,0,1},{0,0,0,0,0,1,0,0,0},{0,1,0,0,0,1,0,1,0},{0,0,1,1,1,0,0,0,1},{1,0,0,0,0,0,0,1,1},{0,1,0,0,1,0,1,0,1},{0,0,1,0,0,1,1,1,0}}
In[53]:= Head[a]
Out[53]= List
In[54]:= IncidenceGraph[a]
During evaluation of In[54]:= IncidenceGraph::list: List expected at position 1 in IncidenceGraph[Automatic,{{0,1,1,0,0,0,1,0,0},{1,0,1,0,1,0,0,1,0},{1,1,0,0,0,1,0,0,1},{0,0,0,0,0,1,0,0,0},{0,1,0,0,0,1,0,1,0},{0,0,1,1,1,0,0,0,1},{1,0,0,0,0,0,0,1,1},{0,1,0,0,1,0,1,0,1},{0,0,1,0,0,1,1,1,0}}]. >>
Out[54]= IncidenceGraph[Automatic,{{0,1,1,0,0,0,1,0,0},{1,0,1,0,1,0,0,1,0},{1,1,0,0,0,1,0,0,1},{0,0,0,0,0,1,0,0,0},{0,1,0,0,0,1,0,1,0},{0,0,1,1,1,0,0,0,1},{1,0,0,0,0,0,0,1,1},{0,1,0,0,1,0,1,0,1},{0,0,1,0,0,1,1,1,0}}]
