If the displayed number is wider than the cell width, an ellipsis
indicates “more to the right” (as in 1 = 2,,.). The default cell width is
four characters.
Note the two uses of
(ENTER):
While you’re using the command line
for data entry,
(ENTER)
enters data into a cell. When a cell coordinate
is displayed,
(ENTER
) enters the entire matrix onto the stack.
To enter a vector using the WlatrixWriter application:
1. Press (f^(MATRIX) to display the MatrixWriter screen and menu.
2.
Key in the numbers in the vector, and press
(ENTER)
after each.
3. After you’ve entered all the numbers
in
the vector, press
(ENTER
) to
put the vector on the stack.
Vectors normally use only one row of data, so you don’t need to press
To enter numbers into more than one cell at a time:
1.
Enter the series of numbers into the command line, pressing
(SPC)
between each number.
2,
Press
(ENTER
) to enter the numbers.
To compute elements in the command line as you enter them:

the computation (press
(SPC)
to separate arguments).

the current cell.
