SRow Calculations

The following menu appears whenever you press (R-OP) while a recalled matrix is on the display.

•{Swap} ... {row swap}

•{σRw} ... {product of specified row and scalar}

•{σRw+} ... {addition of one row and the product of a specified row with a scalar}

•{Rw+} ... {addition of specified row to another row}

STo swap two rows

Example To swap rows two and three of the following matrix:

All of the operation examples are performed using the following matrix.

Matrix A =		1	2
	3		4
		5	6

(R-OP)(Swap)

Input the number of the rows you want to swap.

AUBUU

STo calculate the scalar multiplication of a row

Example To calculate the product of row 2 and the scalar 4

(R-OP)(σRw)

Input multiplier value.*

CU

Specify row number.

AUU

* A complex number also can be input as multiplier value (k).

STo calculate the scalar multiplication of a row and add the result to another row

Example	To calculate the product of row 2 and the scalar 4, then add the result to
	row 3

(R-OP)(σRw+)

Input multiplier value.*

CU

Specify number of row whose product should be calculated.

AU

Specify number of row where result should be added.

BUU

*A complex number also can be input as multiplier value (k). 2-39
