HP-50g Algebraic matrix expressions

[peacecalc]

Hello Sleazey,

Matrix is on Stacklevel 2
{row column}
GET

for example:

\[ stacklevel ~~ 2: \left( \begin{array}{rrr} 1 & 2 & 3 \\ 4 & 5 & 6 \\ \end{array} \right)\]

\[ stacklevel ~~ 1: \{ 2\quad 3 \} \]

\[ command:\quad GET \]

\[ returns: 6 \quad (element \quad second \quad row \quad third \quad column) \]


For this approach your matrix doesn't need to be stored in variable.
