友善|交换。rml()在 Python
中
置换. rmul() : rmul() 是一个 sympy Python 库函数，返回置换的乘积。
语法:sympy.combinations.arranges.arrange.rmul()
返回:排列的乘积。
代码#1 : rmul()示例
# Python code explaining
# SymPy.Permutation.rmul()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.rmul() method
# creating Permutation
a = Permutation([[2, 0], [3, 1]])
b = Permutation([1, 3, 5, 4, 2, 0])
print ("Permutation a - rmul form : ", a.rmul(b))
print ("Permutation b - rmul form : ", b.rmul(a))
输出:
排列 a–rmul 形式:(0 1 3 4 2 5) 排列 b–rmul 形式:(0 2)(1 3)
代码#2 : rmul()示例–2D 置换
# Python code explaining
# SymPy.Permutation.rmul()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from
# sympy.combinatorics.permutations.Permutation.rmul() method
# creating Permutation
a = Permutation([[2, 4, 0],
[3, 1, 2],
[1, 5, 6]])
print ("Permutation a - rmul form : ", a.rmul(a))
输出:
排列 a–rmul 形式:(0 3 5 6 1 2 4)
