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@ `

³~~lxv ` K

A new variable,

@@LXV@@, will be available in the soft menu labels after pressing

J:

Press

‚@@LXV@@ to see the program contained in the variable LXV:

<< OBJ 1 LIST ARRY >>


This variable,

@@LXV@@, can now be used to directly transform a list into a vector.

In RPN mode, enter the list, and then press

@@LXV@@. Try, for example:

{1,2,3} ` @@LXV@@.
