This module implements Pauli algebra by subclassing Symbol. Only algebraic properties of Pauli matrices are used (we do not use the Matrix class).

参见Pauli类的文档以获取示例。

sympy.physics.paulialgebra.evaluate_pauli_product(arg)[源代码]#

Help function to evaluate Pauli matrices product with symbolic objects.

参数:: arg：包含泡利矩阵的符号表达式

实例

>>> from sympy.physics.paulialgebra import Pauli, evaluate_pauli_product
>>> from sympy import I
>>> evaluate_pauli_product(I*Pauli(1)*Pauli(2))
-sigma3

>>> from sympy.abc import x
>>> evaluate_pauli_product(x**2*Pauli(2)*Pauli(1))
-I*x**2*sigma3
