Graphing calculator.

3 - Press the delete key ƒ (also known as function DROP) to eliminate the
number in stack level 1:
4 - Use function
LIST to create a list
5 - Use function
ARRY to create the row vector
These five steps can be put together into a UserRPL program, entered as
follows (in RPN mode, still):
‚å„°@) T YPE! @OBJ @ @OBJ @
„°@) S TACK @DROP „°@) T YPE! ! LIST@ ! ARRY@ `
A new variable, @@CXR@@, will be available in the soft menu labels after pressing
J:
Press ‚@@CXR@@ to see the program contained in the variable CXR:
<< OBJ
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@@.
[[1],[2],[3]] ` @@CXR@@.
Try, for example:
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@@ „Ü „î
³~~cxr ` K
OBJ
