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!

Ran in:
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
