"intersect? ismember? find? i don't know"

You should experiment around with different methods and functions and see what output they give. You will learn about the functionality of functions and get an idea as to where to use them.

I don't know why you think there should be a 4 in the result.

a = [5      20     0     3     5     1     1     10];   
b = [3     5     9    12     4    7     0     0];

intersect(a,b)

ans = 1×3

0 3 5

4 is an error...:D
