MATLAB: How to label sorted variables

Question

Hi,

Let say I have a matrix obtained from sort function,

x = [1,1,3;
     2,2,1;
     3,3,2]

with 1, 2, and 3 represent sorted values of certain variables in vertical manner alongside each column. I want to have another variable that stores the label of corresponding order.

% (e.g. It will be like this)
y = [A,A,B]

How can I do this if I have 7 variables that I want to sort in a 7-by-m matrix?

Thank you.

Maybe what you want:

>> labels=string({"A","B","C"});
>> x = [1,1,3;
     2,2,1;
     3,3,2];
 
>> labels(x)
ans = 
  3×3 string array
    "A"    "A"    "C"
    "B"    "B"    "A"
    "C"    "C"    "B"
