The Intersection, Union, and Difference of Simple Members
Example
Calculate the intersection, union and difference of elements in two sets.
Write the SPL script:
A 

1 
[1,4,6,2,3,9,7] 
2 
[3,7,2,1,9,5,8,7] 
3 
=A1^A2 
4 
=A1&A2 
5 
=A1\A2 
6 
=A2&A1 
7 
=A2\A1 
A1 Set 1
A2 Set 2
A3 The intersection of set 1 and set 2 is: [1,2,3,9,7]
A4 The union of set 1 and set 2 is: [1,4,6,2,3,9,7,5,8,7]
A5 The difference between set 1 and set 2 is: [4,6]
A6 The union of set 2 and set 1 is: [3,7,2,1,9,5,8,7,4,6]
A7 The difference between set 2 and set 1 is: [5,8,7]
It can be seen that the order does matter when calculating union and difference.
