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.)

Put the matrix on the stack, then use DET(1)

The 1 in the parens tells the function how many parameters are to be used. All RPN functions work that way. You put the arguments on the stack, then tell the function how many arguments to use. You wouldn't believe how long it took me to remember that! The people here had to remind me several times.
