I have 2 tables, now i want to check which numbers does not exist in the second table. So for example I have:
A = ["1","2","3"];
B = ["2","3"];
I want to check which number doesn't exist and keep that one.
So:
C = ["1"];

A = ["1","2","3"];
B = ["2","3"];
C=A(~ismember(A,B))
C = "1"

Now i have a list of double ID's.
C=bookings.id(~ismember(bookings.id(:),KopievanPolissenEuropeesche.VarName1(:)))
How can I use this to get only the table rows without common ID?
