I am considering "or" part of the question "how get same elements in 2 arrays?"

Use Intersection between two array, see detail here

See the following example, where A and B are two arrays having any lengths

>> A=1:10;
>> B=[2 3 4 5 200 100 101];
>> result=intersect(A,B) 

Command Window:

result =
     2     3     4     5

Hope it Helps!
