I have twos lists I want to compare with one another and delete the cases
where the elements in list1 match list2. For example:
list1={21,41,61,71,81}
list2={71,73,75,77,79,81}
I want the new list3 to read:
list3={21,41,61}
It seems to me that the following should work:
list3=DeleteCases[list1,list2]
Any thoughts?
Thanks
Shawn
