CUDUEU

(Data is input into the highlighted cell. Each time you press U, the highlighting moves to the next cell to the right.)

•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.

SDeleting Matrices

You can delete either a specific matrix or all matrices in memory.

STo delete a specific matrix

1.While the Matrix Editor is on the display, use D and A to highlight the matrix you want to delete.

2.Press (DEL).

3.Press (Yes) to delete the matrix or (No) to abort the operation without deleting anything.

STo delete all matrices

1.While the Matrix Editor is on the display, press (DEL • A).

2.Press (Yes) to delete all matrices in memory or (No) to abort the operation without deleting anything.

IMatrix Cell Operations

Use the following procedure to prepare a matrix for cell operations.

1.While the Matrix Editor is on the display, use D and A to highlight the name of the matrix you want to use.

You can jump to a specific matrix by inputting the letter that corresponds to the matrix name. Inputting ?G(N), for example, jumps to Mat N.

Pressing (Ans) jumps to the matrix current memory.

2.Press Uand the function menu with the following items appears.

•{R-OP} ... {row operation menu}

•{ROW}

•{DEL}/{INS}/{ADD} ... row {delete}/{insert}/{add}

•{COL}

•{DEL}/{INS}/{ADD} ... column {delete}/{insert}/{add}

•{EDIT} ... {cell editing screen}

All of the following examples use Matrix A.
