HP49-50G : Matrix & Strings

[Gil]

Absolutely amazing!

I didn't think it might be possible to find a solution to that "riddle".

Your tip worked beyond my expectations.

In HP50G (EMU48)
1) I can have a matrix by {9 9} RANM that I duplicate with DUP command.
2) Then I use my HP program to convert that matrix to a string.
3) Then, always in my HP, I copy that stack

4) And paste it into the command line of the Maxima software.
5) ENTER in Maxima
6) Always in Maxima software, I write
invert (%) ENTER.
7) Then, still in Maxima software, I copy the resulted matri with its fractions.

8) And paste it into the stack of the HP50G.
9) With another HP50G program, I transform the above stack content (a string) in the HP50G into a matrix compatible with HP50G Matrix format.
10) And execute *, to get exactly the expected Identity Mstrix!

Many, many thanks, David.
