HP Prime - Display one matrix element in RPN mode

HP Recommended

How do you display one element of a matrix in RPN mode?

 

The user manual instructs to enter M2(1,2) to return the 2 element of the first row, however; in RPN mode this produces "syntax error"

 

There seem to be a lot of functionality lost in RPN mode. Is there a separate guide that provides instructions on how to use the calculator in RPN mode?

 

I don't mean stack operations and etc. I have been using an HP35s in RPN mode for years. I want to learn how to take advatange of the capability this calculator offers, specifically with regard to matrices, with using RPN mode.

There might be a simpler way, but this works. Notice the single quote marks (accessed by pressing Shift parentheses):

 

'M2(1,2)'

Enter

Eval

 

Eval is accessed by pressing Shift comma.

 

Hope that helps!  Somebody else might suggest a more efficient method.

1

M1(2) ENTER

 

The reason is that you have to specify the number of arguments to the M1 function since it takes a variable number.
