If you have selected the textbook display option (using H@) D ISP! and
Textbook ), the matrix will look like the one shown above.
Otherwise, the display will show:
The display in RPN mode will look very similar to these.
Typing in the matrix directly into the stack
The same result as above can be achieved by entering the following
directly into the stack:
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~aK .
