Find Index Positions of a Small Array values in a Global Array

Hi guys,

I have a "global" array: Global = [1; 4; 6; 9; 13; 17; 26; 33; 47].

And a "small" array: Small = [6; 26; 47]

How can I find the positions of the "small" array values into the "Global" array? The result would be: Result = [3 7 9]

Thanks! Nicolas

G = [1; 4; 6; 9; 13; 17; 26; 33; 47];
S= [6; 26; 47]; 
find(ismember(G,S))

ans =

       3
       7
       9
