S Row Calculations
The following menu appears whenever you press (R-OP) while a recalled matrix is on the
display.
• {Swap} ... {row swap}
• { sRw} ... {product of specified row and scalar}
• { sRw+} ... {addition of one row and the product of a specified row with a scalar}
• {Rw+} ... {addition of specified row to another row}
S To 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
S To calculate the scalar multiplication of a row
Example To calculate the product of row 2 and the scalar 4
(R-OP)(sRw)
Input multiplier value.*
CU
Specify row number.
AUU
* A complex number also can be input as multiplier value (k).
S To 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)(sRw+)
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).
