from_scipy_sparse_matrix(A, create_using=None, edge_attribute='weight')[source]

Return a graph from scipy sparse matrix adjacency list.

Parameters :

A: scipy sparse matrix

An adjacency matrix representation of a graph

create_using: NetworkX graph

Use specified graph for result. The default is Graph()

edge_attribute: string

Name of edge attrbute to store matrix numeric value. The data will have the same type as the matrix entry (int, float, (real,imag)).
