[BUG] Using distance matrix to compute the Vietoris Rips Persistance

1

Hi! I'm trying to compute the Vietoris Rips persistence of my graph using its distance matrix. I have an unweighted, undirected graph and its distance matrix is: dist_matrix = np.array([[0,1,2,4,4],[1,0,1,3,3],[2,1,0,2,2],[4,3,2,0,2],[4,3,2,2,0]])...
