SymmetricDifference

SymmetricDifference[list1,list2,]

给出列表 listi 的对称差.

更多信息和选项

  • SymmetricDifference[list1,list2] 给出在 list1list2 中但不同时在两者中的元素的排序后的列表.
  • SymmetricDifference[list1,list2,] 给出在奇数个 listi 中出现的元素的排序后的列表.
  • listi 必须有相同的标头,但不必是 List.
  • SymmetricDifference[list1,list2,,SameTesttest]listi 中的每对元素应用 test,以确定是否应将其视为等同.

属性和关系  (6)

SymmetricDifference[] 返回 {}

SymmetricDifference[list,{}] 返回 list

SymmetricDifference[l1,l2] 返回与 SymmetricDifference[l2,l1] 一样的元素:

SymmetricDifference[l1,l2] 等价于 Union[Complement[l1,l2],Complement[l2,l1]]

SymmetricDifference[l1,l2] 等价于 Complement[Union[l1,l2],Intersection[l1,l2]]

SymmetricDifference[l1,l2,] 返回在奇数个列表中出现的元素:

UniqueElements[{l1,l2,}]返回只在其中一个列表中出现的元素:
