Re: RREF working, but rref & REF not working?

Ok, something is screwy.

REF and rref do work in Debug4X(49g+) and Power48 (49g), so it's me.

After another 45 mins setting all my flags and all my CALCULATOR modes
and all my CAS modes and all my DISPLAY modes to match Debug4X, I still
receive "bad argument type" for these two functions.

And if I type "VER", my calc returns "VER".

I feel very dumb. Please help.

Hello,

I'm doing some linear algebra. I have a 49g+ with the latest rom. If I
input matrices from my textbook or matrices from the HP49g+ manual
(pages 11-41, 11-42), RREF works, but REF and rref return "bad argument
type".

The matrices are type MATRX in my file manager. I checked my flags in
the HP "advanced users reference manual" and they are good.

Am I doing something wrong, or are these functions broken or
depracated?



Thank you,
