This variable,

@@CXR@@, can now be used to directly transform a column vector to a

row vector. In RPN mode, enter the column vector, and then press

@@CXR@@. Try,

for example:

[[1],[2],[3]] ` @@CXR@@.

After having defined variable

@@CXR@@, 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 @@CXR@@ „Ь „о

resulting in:

Transforming a list into a vector

To illustrate this transformation, we’ll enter the list

{1,2,3} in RPN mode.

Then, follow the next exercise to transform a list into a vector:

1 - Use function OBJ to decompose the column vector

2 - Type a 1 and use function LIST to create a list in stack level 1:

3 - Use function ARRY to create the vector

These three steps can be put together into a UserRPL program, entered as
follows (in RPN mode):

‚å„°@)TYPE! @OBJ @ 1 ! LIST@ ! ARRY@ `
