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@@.
