I do not think that the 39gs can do matrix with symbols (letters). Even with "formal variables" it does not work.


See the User's Guide manual p13-20 for "formal variables"


Also see "Mastering the hp 39gs & hp 40gs" chapter 30 for more guidance on working with matrices on the 39gs.


The above mentioned documents are available here:

HP-39gs manuals



If you need the symbiloc matrix functions, you might wish to get a HP Prime.

Try the emulator:

HP Prime Virtual Calculator - Windows

HP Prime Virtual Calculator - MacOS DMG

Thank you for the link to the virtual calculator.

I did not know that it was for free, and thought it would not work on my Windows version, but it does!
