EIGENV in RPN mode

[Jean-Michel]

Hello all

Sorry for bothering you with such a low level topic, but I can't find out how to use the EIGENV command (be it with a predefined M1 matrix, or a matrix listed in the command, or above in the stack) when in RPN mode, which is my default setting.
I just get "Syntax error" as a result.
No issue when in Textbook or Algebraic mode.

Is it me or is this kind of command not compatible with RPN? This may have been discussed already but I just don't have much time to dig into the archives right now.

Many thanks Advanced and kind regards.
