### 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
RCI rounds the row number to the nearest integer, and treats vector arguments as column
vectors.
Access:
Input/Output:

### RCIJ

RCIJ
Type:
Command
Description: Add Multiplied Row Command: Multiplies row i of a matrix by a constant x
product to row j of the matrix, and returns the modified matrix; or multiplies element i of a
vector by a constant x
vector. RCIJ rounds the row numbers to the nearest integer, and treats vector arguments as
column vectors.

### RCL

Type:
Command Operation
Description: Recall Command: Returns the unevaluated contents of a specified variable.
