graphdot.graph.reorder.rcm module

graphdot.graph.reorder.rcm.rcm(g)

Compute the reverse Cuthill-Mckee permutation of a graph. Note that the method does NOT modify the graph, but rather just returns a permutation vector that can be used by Graph.permute to achieve the actual reordering.

Parameters:g (Graph) – The graph to be reordered. Returns:perm – Array of permuted node indices. Return type:numpy.ndarray
