List Catalog and Editor

You can create lists of real numbers, complex numbers, expressions, matrices, and
other lists. You can also perform certain mathematical operations on lists. Press S 7
to display the List Catalog. Up to ten lists can be stored in the catalog, each named
L1–L9 or L0. The menu items in the List Catalog are as follows:
—Opens the selected list so that you can add or change elements. You can
also just tap the list name.
—Deletes the contents of a selected list.
—If present, sends a highlighted list to another HP Prime calculator.
When you select a list, the List Editor opens. This is where you add elements to, or
change elements in, a list. When you first open a list, it is blank. To enter an element,
start keying it. The menu items in the List Editor are as follows:
—Copies the selected element to the entry line, where it can be edited. This
item is only visible when an element in the list is selected.
—Opens an editing options menu. For more information on this menu, see
"Matrix Catalog and Editor" on page 49.
—Move the cursor to the specified element in the list. This option is
especially useful for very large lists.
or
—Sets how the cursor moves after you press E. The options are Down, Right, and None.
Enter the first element in your list and press E or tap
the next row. Repeat until you have added all the elements you want to add. When you
have completed the list, press S 7 to return to the List Catalog.
In programs and in Home view, you can refer to a list by its name (L1, L2, and so on).
For example, suppose L2 is composed of {5,6,1,5,8}. In Home view, you could enter
5*L2. The result displayed is {25,30,5,25,40}. Note that each item in the new list
is five times its corresponding item in L2. Note too that a list is represented by a pair of
braces—{}—with each item separated by a comma. If you want to store your result in,
say, list L6, just tap
, enter L6, and press E. If you then open the List
Catalog, you would find that L6 has been populated.
You can create a list in Home view by pressing S8 and entering each element, separated by a comma.
Numerous list-related functions are available on the Math menu (see "Math menu" on page 46).

Matrix Catalog and Editor

You can create both matrices and vectors. Press S 4 to display the Matrix Catalog. Up
to ten matrices or vectors can be stored in the catalog, each named M1–M9 or M0. The
menu items in the Matrix Catalog are as follows:
—Opens the selected matrix or vector so that you can add or change
elements. You can also tap the matrix name.
—Deletes the contents of the selected matrix or vector.
—Changes the selected matrix into a vector.
