9. Vector Calculations
To perform vector calculations, use the Main Menu to enter the
Run-Matrix
mode, and then
press

(M
⇔
V).
A vector is defined as a matrix that is either of the two following forms:
m
(rows)
×
1 (column)
or 1 (row)
×
n
(columns).
The maximum allowable value that can be specified for both
m
and
n
is 999.
You can use the 26 vector memories (Vct A through Vct Z) plus a Vector Answer Memory
(VctAns) to perform the vector calculations listed below.
• Addition, subtraction, multiplication
• Scalar multiple calculations
• Dot product calculations
• Cross product calculations
• Determination of the vector norm (size)
• Determination of the angle formed by two vectors
• Determination of the unit vector
Important!
• You can input either an upper-case X (
a
+
(X)) or lower-case
x
(
v
) for vector memory
“Vct X”. Both “Vct X” and “Vct
x
” refer to the same memory area.
About Vector Answer Memory (VctAns)
The calculator automatically stores vector calculation results in Vector Answer Memory. Note
the following precautions about Vector Answer Memory.
• Whenever you perform a vector calculation, the current Vector Answer Memory contents are
replaced by the new result. The previous contents are deleted and cannot be recovered.
• Inputting values into a vector does not affect Vector Answer Memory contents.
• Vector calculation results are also stored in Matrix Answer Memory (MatAns).
