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 RRY >>
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@@.
After having defined variable @@LXV@@, we can use it in ALG mode to transform a
list into a vector. Thus, change your calculator’s mode to ALG and try the
following procedure:
{1,2,3} ` J @@LXV@@ „Ь „о, resulting
in:
Transforming a vector (or matrix) into a list
To transform a vector into a list, the calculator provides function AXL. You can
find this function through the command catalog, as follows:
‚N~~axl~@@OK@@
As an example, apply function AXL to the vector [1,2,3] in RPN mode by
using: [1,2,3] ` XL. The following screen shot shows the application of
function AXL to the same vector in ALG mode.
