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)

Yes, you should do: adj = numpy.array(matrix) g = Graph() g.add_edge_list(transpose(adj.nonzero())) Best, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
