I have a set of categorical variables

A = {'NY','Boston'}

How can one sort A to B as

B = {'Boston','NY'}

I tried sort but does not work.

This is very sruprising that sort doesn't work for you (I'm wondering how is this even possible).

A = {'NY', 'Boston'};
sort(A)
 1×2 cell array
    {'Boston'}    {'NY'}

I think in general a better pratice to define a proxy variable (Boston = 1 and NY =2) and work on the proxy variable instead of dealing with letters.

As Ive Ive suggested: the sort function will do what you need:

B = categorical({'NY','Boston'});
sort(B)
ans = 1×2 categorical array
     Boston      NY
