comparing 2 arrays

I have an array A=[1 2 3] B=[1 2 5] I want to get the elements that are present only in one of the arrays stored in A and B like A=[3] and B=[5] because 1 and 2 are present in both the arrays.How do I achieve that?

Answer 1

[Jan]

A = [1 2 3]
B = [1 2 5]

A2 = setdiff(A, B);
B2 = setdiff(B, A);

Or if you really need the same names as output:

A2 = setdiff(A, B);
B  = setdiff(B, A);
A  = A2;

EDIT: corrected as per Jan's observation

u = intersect(A,B);
A = setdiff(A,u);
B = setdiff(B,u);

[Jan]

SETINTERSECT? I assume you mean INTERSECT.
