Build a graph from the adjacency matrix

Hi there !

I'm wondering if possible to build a graph starting from the adjacency
matrix.

Having such a matrix

matrix = [[1.0, 0.0], [1.0, 1.0]]

I'd like to build its graph

(0) --- (0)

(1) --- (0)

(1) --- (1)

Thank you in advance.

Marco.

Yes, you should do:

    adj = numpy.array(matrix)
    g = Graph()
    g.add_edge_list(transpose(adj.nonzero()))

Best,
