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.
