so, i have an array A=(1,2,3,4,5,6,7,8,9) and another array containing indexes B=(1,1,3,6,7,5,4). How to get a third one based on B such that C=[A(1),A(1),A(3),A(6),A(7),A(5),A(4)]?
I know how to do this by looping through b with i=1:length(B) and taking C(i)=A(B(i)) but would prefer to do this without any loop due to my real data being considerably larger than this example.
I'm new to matlab, any help is highly appreciated. thanks!
