MATLAB: I can’t create a graph from the adjacency matrix

Question

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).

Answer 1

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.
