RPN Mode: Possible to use advanced matrix operations?

[johan162]

Since I'm used to the older HP calculators I prefer the RPN in the normal calc (non-CAS).

However I can't seem to use some of the common matrix operations like eigenvalues etc. since that always gives me "Syntax Error". Switching to non-RPN mode they (of course) work just fine.

Is it really not possible to use those kind of "advanced" (really?) operations in RPN mode?

(That would make the RPN mode severely crippled and inconsistent since it is possible to, for example, compute the determinant in RPN mode - hopefully I've just missed something.)
