NetworkX-simple graph

 import networkx as nx
 import matplotlib.pyplot
 import scipy.io as sio
 import numpy as np

 load_path='H:/summer/datasets_read/chb01/Seizure/cut/wc/03.mat'
 load_data=sio.loadmat(load_path)

 # print(type(load_data))
 # print(load_data.keys())
 # print(load_data.values())
 print(load_data['R'])

 Matrix=np.array(load_data['R'])
 g = nx.Graph()

 for i in range(len(Matrix)):
     for j in range(len(Matrix)):
         g.add_edge(i,j)

 nx.draw(g)
 matplotlib.pyplot.show()

Guess What??

Funny ,HA~
