Hello,
I'm trying to create a matrix with RANDMAT in RPN mode. The arguments are e.g.

Code:

 'M0' 

   5

   2

When I execute RANDMAT I get the error messagebox RANDMAT(5,2). Obviously, the 'M0' on the stack is ignored.
Is this a bug or am I doing something wrong?

Regards
Bernd

BTW: The RANDMAT is only function where I have to specify a variable as target. This looks inconsistent to me compared to e.g. MAKEMAT or IDENMAT.

Edit: Subject.

You could try RANDMAT(3) as you are taking three elements off the stack. I understand that in RPN for most functions you must tell the calc how many objects should be consumed

Indeed.

Since RANDMAT can consume a variable number of arguments, specifying (3) will work. It isn't that "most" commands in RPN need a specifier, rather those can can consume a variable number of arguments need a specifier else they will default to the lowest number they can take.

Hello,
Thanks Terje and Tim for the help.
I have overlooked this in the manual.
