Python| SymPy Permutation.get_adjacency_matrix() 方法

Permutation.get_adjacency_matrix() :get_adjacency_matrix()是一个 sympy Python库函数,用于计算参数中排列的邻接矩阵。

代码 #1:get_adjacency_matrix() 示例

# Python code explaining
# SymPy.Permutation.get_adjacency_matrix()
  
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
  
# Using from 
# sympy.combinatorics.permutations.Permutation.get_adjacency_matrix() method 
  
# creating Permutation
a = Permutation([2, 0, 3, 1, 5, 4])
  
b = Permutation([3, 1, 2, 5, 4, 0])
  
print ("a - get_adjacency_matrix : \n", a.get_adjacency_matrix())
print ("b - get_adjacency_matrix : \n", b.get_adjacency_matrix())

输出 :
