3 - Use function ARRY to build the column vector

These three steps can be put together into a UserRPL program, entered as

follows (in RPN mode, still): ‚å„°@)TYPE! @OBJ@ 1 + !ARRY@

`³~~rxc` K

A new variable, @@RXC@@, will be available in the soft menu labels after pressing

Press ‚@@RXC@@ to see the program contained in the variable RXC:

<< OBJ 1 +  RRY >>

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
