Assigning and Editing Vector Variable Data
Important:
The following operations are not supported by the Vector Editor:
m
,
1m
(M–),
1t
(STO). Pol, Rec, ÷R, and multi-statements also
cannot be input with the Vector Editor.
To assign new data to a vector variable:
1. Press
1
5
(VECTOR)
1
(Dim), and then, on the menu that appears,
select the vector variable to which you want to assign data.
2. On the next menu that appears, select dimension (
m
).
3. Use the Vector Editor that appears to input the elements of the vector.

To edit the elements of a vector variable:
1. Press
1
5
(VECTOR)
2
(Data), and then, on the menu that appears,
select the vector variable you want to edit.
2. Use the Vector Editor that appears to edit the elements of the vector.
• Move the cursor to the cell that contains the element you want to change,
input the new value, and then press
=
.
To copy vector variable (or VctAns) contents:
1. Use the Vector Editor to display the vector you want to copy.
• If you want to copy VctA, for example, perform the following key operation:
1
5
(VECTOR)
2
(Data)
1
(VctA).
• If you want to copy VctAns contents, perform the following to display the
VctAns screen:
A1
5
(VECTOR)
6
(VctAns)
=
.
2. Press
1t
(STO), and then perform one of the following key operations
to specify the copy destination:
-
(VctA),
$
(VctB), or
w
(VctC).
• This will display the Vector Editor with the contents of the copy
destination.
Vector Calculation Examples
The following examples use VctA = (1, 2) and VctB = (3, 4) from
1
, and VctC =
(2, –1, 2) from
2
. You can input a vector variable into a key operation by
pressing
1
5
(VECTOR) and then pressing one of the following number
keys:
3
(VctA),
4
(VctB),
5
(VctC).
