Manipulating columns and rows
To insert a column
1. Move the cursor to the column where you wairt the new coliuun to
appear.
2. Press +COL. A coliurm of zeros is inserted.
Note that the +COL command is on the second page of the menu, so
you may need to press (NXT) to display it.
You can also add a column to an an’ay without using Matrix Writer.
See “To insert one or more new columns into an array” on page 5-
11.
To add a column to the right oF the last column of data
1. Move the cursor to the right of the last column of data.
Pressing © ® will move the cursor directly to the last column of data.
You then press ® to move to the next column.
2. Enter an object.
3.
Press
(ENTER)
to move your object to the higlilighted cell.
The rest of the column fills with zeros and your array now includes this
new colunrm.
To delete a column
1. Move the cxu'sor to the colunm you want to delete.
2. Press -COL.
Note that the -COL command is on the second page of the menu, so you
may need to press (NXT) to display it.
To insert a row
1. Move the cursor to the row where you want the new row to appear.
2. Press +ROW. A row of zeros is inserted.
Note that the +ROW command is on the second page of the menu, so
you may need to press (NXT) to display it.
You can also add a row to an array without using Matrix Writer.
See “To insert one or more new rows into a matrix” on page 5-11.
