A=[1,2,3,4,5,7,1];

B=[1,3,5,6];

Determine which elements of B are also in A as well as their corresponding locations in A.

Syntax: [yn,pos]=ismember(B,A);

Output: yn=[1,1,1,0] % if an element of B is found in A, then yn returns 1 (ture), elsewhere, it returns 0 (false).

            pos=[1,3,5,0] % find the lowest index of locations. The lowest position index to B(1) is A(1).
