RCI
Type: Command
Description: Multiply Row by Constant Command: Multiplies row n of a matrix (or element n of a vector) by
a constant x
factor
, and returns the modified matrix.
RCI rounds the row number to the nearest integer, and treats vector arguments as column
vectors.
Access: !Ø
CREATE ROW RCI ( Ø is the left-shift of the 5key).
!´
MATRIX ROW RCI ( ´ is the left-shift of the Pkey).

RCIJ
Type: Command
Description: Add Multiplied Row Command: Multiplies row i of a matrix by a constant x
factor
, adds this
product to row j of the matrix, and returns the modified matrix; or multiplies element i of a
vector by a constant x
factor
, adds this product to element j of the vector, and returns the modified
vector. RCIJ rounds the row numbers to the nearest integer, and treats vector arguments as
column vectors.
Access: !Ø
CREATE ROW RCIJ ( Ø is the left-shift of the 5key).
