I just tried the matrix inversion command with a simple 4x4 matrix. Calling M-1 directly from the keyboard makes the calculator shut down (!). Sometimes the VERS screen is displayed instead.
However, if the same M-1 command is used from within a program, everything works fine:
001 LBL AUsed this way, the command is executed as expected. The same applies to M-1 calls from the library, e.g. the matrix editor MED.
002 M-1
003 END
All this applies to Version 3.1 3325 as well as the new 3.2 3350 (updated a few minutes ago). So, is it the firmware or is there a problem with my hardware?
