„Ô

„Ô 2.5\ ‚í 4.2 ‚í 2 ™

‚í

„Ô .3 ‚í 1.9 ‚í 2.8 ™

‚í

„Ô 2 ‚í .1\ ‚í .5

Thus, to enter a matrix directly into the stack open a set of brackets (

„Ô

)

and enclose each row of the matrix with an additional set of brackets

(„Ô). Commas (‚í .) should separate the elements of each

row, as well as the brackets between rows.

For future exercises, let’s save this matrix under the name A. In ALG mode

use

K~a

. In RPN mode, use

³~a K
