I want to get a transposition symbol of matrices like ^t(1 2 3), as title. I used the macro \prescript (in mathtools) at present.

There is no any problem occured, these packages' macros work well. I just want to know whether there is some rules to help distinguishing them.

And what is wrong with that? You should add the actual problem description. –  Thorsten Donig Jan 28 '11 at 17:17
    
Oh, I just want to konw if there is some kind of rules or specifications to help choosing the packages in this situation. –  user3214 Jan 29 '11 at 2:14

Why should there be rules? But possibly there are several (identical) solutions. –  Thorsten Donig Jan 30 '11 at 20:30

If all the packages provide a solution, and they are equally easy to use, there's not really any way to choose. But if you are using, say, mathtools anyway (it provides many nifty extensions of amsmath), I would probably use its solution, in order to minimize the number of \usepackages, and thus reducing the risk of conflicts. Also, you could look at the documentations for the various packages and see if they are actively maintained. –  Villemoes Feb 20 '11 at 7:27
    
@Villemoes: Maybe you could add that as an answer (so that this question goes of the unanswered list). –  Caramdir Feb 20 '11 at 17:03
