# Transforming A Column Vector Into A Row Vector - HP F2226A - 48GII Graphic Calculator User Manual

Graphing calculator.

A new variable, @@RXC@@, will be available in the soft menu labels after pressing
J:
Press ‚@@RXC@@ to see the program contained in the variable RXC:
This variable, @@RXC@@, can now be used to directly transform a row vector to a
column vector. In RPN mode, enter the row vector, and then press @@RXC@@. Try,
for example: [1,2,3] ` @@RXC@@.
After having defined this variable , we can use it in ALG mode to transform a
row vector into a column vector. Thus, change your calculator's mode to ALG
and try the following procedure: [1,2,3] ` J @@RXC@@ „ Ü „
î, resulting in:

## Transforming a column vector into a row vector

To illustrate this transformation, we'll enter the column vector
[[1],[2],[3]] in RPN mode. Then, follow the next exercise to
transform a row vector into a column vector:
1 - Use function OBJ
to decompose the column vector
2 - Use function OBJ
to decompose the list in stack level 1:
<< OBJ
1 +
ARRY >>
