Hi, I'm trying to create an undirected graph from my adjacency matrix. This is my code:
undirected_graph=graph(undirected_network);
The error I receive is the following one:
Error using digraph/subsref (line 8)
Unsupported graph indexing.
The adjacency matrix is symmetric (I tested it with the function issymmetric) and its diagonal values are all zero (the graph has no loops).

I suspect you've created a digraph object and stored it in a variable named graph, which will prevent you from calling the graph function to create a graph object. Rename that variable.
