remove common elements from 2 array
Show older comments
Hello Everyone,
I have two array Arr1 = [301;302;303;601;602;603]
and I have another Arr2 = [101;102;301;302;303;601;602;603;1010;1200;1249;1352]
I want to remove the common elements from both arrays
so my result should look like
Arr3 = [101;102;1010;1200;1249;1352]
How can I solve this problem

What have you tried so far? Have you looked at INTERSECT?

What if both Arr1 and Arr2 have elements are not part of the intersection? What do you want the output to be?

Ricky, what cyclist is saying is that your example misses an important edge condition. There are two obvious solutions that give the same result for your example arrays, but which behave very different in general.

What do you want the result to be when
Arr1 = [1; 2; 3; 4; 5; 6];
Arr2 = [1; 2; 3; 7; 8; 9];
?

Acommon = intersect(Arr1,Arr2)
Arr3 = setxor(Arr2,Acommon)
will give you the result you mentioned, but see my comment.
