Vector Calculations (VCT)
(fx-570MS/991MS only)
Use the VCT Mode to perform 2-dimensional and 3-dimensional vector
calculations. To perform a vector calculation, you first assign data to
special vector variables (VctA, VctB, VctC), and then use the variables
in the calculation as shown in the example below.
To assign (1, 2) to VctA and (3, 4) to VctB, and then perform
the following calculation: (1, 2) + (3, 4)
1. Press
NNN3(VCT) to enter the VCT Mode.
2. Press
!5(VCT) 1(Dim) 1(A).
Vc t A ( m ) m?
0.
3. Input the dimensions of VctA: 2
=.
• This will display the Vector Editor for
input of the 2-dimensional vector for
VctA.

• This will display the Vector Editor for input of the 2-dimensional
vector for VctB.
6. Input the elements of VctB: 3
= 4 =.
7. Press
A to advance to the calculation screen, and perform the
calculation (VctA + VctB):
15(VCT) 3(Vct) 1(A) +15
(VCT)
3(Vct) 2(B) =.
• This will display the VctAns screen with the calculation results.

Note: “VctAns” stands for “Vector Answer Memory”. See “Vector
Answer Memory” for more information.

Whenever the result of a calculation executed in the VCT Mode is a
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 operation:
15(VCT) 3(Vct) 4(Ans).
• 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.
