Thread Subject: get position of elements of subvector in a vector

Hello I am looking for a quick way to find positions in a vector of elements of subvector

Ex :

function([1 1 2 2 3 4 5 6 7 7 8],[1 2 7]) = [1 2 3 4 9 10]
I could loop and do a find on 1,2,7 but looking for a vectorized way.

Cheers

x=[1 1 2 2 3 4 5 6 7 7 8];
y=[1 2 7];
anwer = find(ismember(x,y));
