How to find an array with all common elements?

Hi all,

Suppose I have the following two arrays:

a= [1 1 1 0 1];
b= [1 0 1 1 0];

I want to find an array that contains each element common to both a and b. So, the elements can be repeated and they have to be in order. I will appreciate any help on this. Thanks!

a= [1 1 1 0 1];
b= [1 0 1 1 0];
a(a == b)

ans = 1×2

1 1
