[Numpy-discussion] Networkx graph - numpy array - networkx.has_path() function

Hi experts! I wanna use networkx.has_path(). This is applies, necesary, to a networkx graph. I have a adjacency matrix of a undirected graph (M, wich is a numpy matrix (array of N x N elements)). How can I do for use M in  networkx.has_path()? If I must transform M into a networkx graph: how can I do that? Waiting for your answers. Thanks a lot!! José Luis
