Compare two Vectors and multiply equal entries

Hi,

I got an orignal dataset with a set of IDs and a unique characteristic value for each ID. For example ID A has the characteristic value 1, ID B has 2 ID C has 3 and so on. I got a second array with entries like AABBCDDDEFFE and I want to create a resulting array that looks like 112234445665, how would you do that?

Thanks!

ID = 'ABCDEF';
val = 1:6;
arr = 'AABBCDDDEFFE';
[X,Y] = ismember(arr,ID);
out = val(Y(X))

out = 1×12

1 1 2 2 3 4 4 4 5 6 6 5
