u To input cell values
○○○○○
Example To input the following data into Matrix B :
123
456
c (Selects Mat B.)
w
bwcwdw
ewfwgw
(Data is input into the highlighted cell.
Each time you press w, the highlighting
move to the next cell to the right.)
# You can input complex numbers into the
cell of a matrix.
# Displayed cell values show positive
integers up to six digits, and negative
integers up to five digits (one digit used for
the negative sign). Exponential values are
shown with up to two digits for the
exponent. Fractional values are not
displayed.
# You can see the entire value assigned to a cell
by using the cursor keys to move the highlight-
ing to the cell whose value you want to view.
# The amount of memory required for a matrix is 9
bytes per cell. This means that a 3 × 3 matrix
requires 81 bytes of memory (3 × 3 × 9 = 81).
Inputting complex numbers into a matrix
doubles the amount of memory used.
