CHAPTER 5
2. Matrix Calculations
Functions except for complex numbers can be used.
Additionally, [C OPE] and [D MATH] of the menu include the special matrix
functions.
<Example>
Assume that mat A is
and mat B is
.
Calculate the addition of mat A and mat B, and the square of mat A.
The calculation is done on the home screen.
1. mat A + mat B
¬ (Clears the home screen.)
A 1+ A 2
3. Square of mat A.
¬
A 1 ®
If the answer matrix and the equation cannot be
displayed on one screen, the equation disappears and
only the answer is displayed.
To show the part of the answer which cannot be displayed on the screen, press
<, >, ≤, or ≥ to scroll the screen in a desired direction.
Additionally, using the last answer function, the answer can be temporarily stored
into a blank matrix file like “Ans =
>
mat H”. After that, press B 8 to
display the list in the edit mode.
2. Press ® to obtain the answer in the matrix format.
