Whenever the result of a calculation executed in the VECTOR Mode is a
vector, the VctAns screen will appear with the result. The result also will be
assigned to a variable named “VctAns”.
vector, the VctAns screen will appear with the result. The result also will be
assigned to a variable named “VctAns”.
The VctAns variable can be used in calculations as described below.
• To insert the VctAns variable into a calculation, perform the following key
• To insert the VctAns variable into a calculation, perform the following key
operation:
(VECTOR)(VctAns).
• Pressing any one of the following keys while the VctAns screen is displayed
will switch automatically to the calculation screen:
, , , . The
calculation screen will show the VctAns variable followed by the operator
for the key you pressed.
for the key you pressed.
Assigning and Editing Vector Variable Data
Important: The following operations are not supported by the Vector Editor:
6, 6(M–), =(STO). Pol, Rec, and multi-statements also cannot
be input with the Vector Editor.
To assign new data to a vector variable:
6, 6(M–), =(STO). Pol, Rec, and multi-statements also cannot
be input with the Vector Editor.
To assign new data to a vector variable:
1. Press
(VECTOR)(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 assign (2, –1, 2) to VctC
(VECTOR)(Dim)(VctC)(3)

To edit the elements of a vector variable:
1. Press
(VECTOR)(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:
(VECTOR)(Data)(VctA).
• If you want to copy VctAns contents, perform the following to display the
VctAns screen:
(VECTOR)(VctAns).
2. Press
=(STO), and then perform one of the following key operations
to specify the copy destination:
(VctA), (VctB), or @(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
(VECTOR) and then pressing one of the following number
keys:
(VctA), (VctB), (VctC).
