HP-50g - Define functions with matrices inside

[roem76]

I couldn't make it work in ALG-mode either but I have to say I'm not used to ALG-mode.

But it's rather easy to create a small RPN-program that takes two arguments (M and R) from the stack and does what you want. Not sure how to program that in ALG-Mode though.

Program listing in RPN

\<< \-> M R
\<< [[ 'COS(R)' 1 ][ 1 'COS(R)' ]] M * \->NUM \>>
\>>

'A'
STO // store the program in A

How to use it in RPN-mode:
1.5 // M
30.0 // R
[A] // with softmenu, press [VAR] and [NXT] till you see [A]

Output:
[[ 1.2990 1.5000 ][ 1.5000 1.2990]]

But once created it will work in ALG-mode as well:
'->NUM(A(1.5,30.0))' // ->NUM from the cat menu
