從excel中讀數據存入矩陣

1、

#從excel中讀入鄰接矩陣，space_l和space_p
import numpy as np
import xlrd

def excel2m(path):#讀excel數據轉爲矩陣函數
    data = xlrd.open_workbook(path)
    table = data.sheets()[0]
    nrows = table.nrows  # 行數
    ncols = table.ncols  # 列數
    datamatrix = np.zeros((nrows, ncols))
    for x in range(ncols):
        cols = table.col_values(x)
        cols1 = np.matrix(cols)  # 把list轉換爲矩陣進行矩陣操作
        datamatrix[:, x] = cols1 # 把數據進行存儲
    return datamatrix
ml = excel2m("gongjiao_l.xlsx")
mp = excel2m("gongjiao_p.xlsx")

2、

#從矩陣形成圖

import matplotlib.pyplot as plt
import networkx as nx
G = nx.Graph()
for i in range(len(ml)):
    for j in range(len(ml)):
        if  ml[i,j]==1:
            G.add_edge(i, j)
