Vector Calculation Precautions
• When calculating a dot product, cross product, and angle formed by two vectors, the
dimensions of the two vectors must be the same. Also, a cross product’s dimensions must
be 1 × 2, 1 × 3, 2 × 1, or 3 × 1.
• Vector calculations are performed independently for each element, so it may take some time
before calculations results are displayed.
• The calculation precision of displayed results for vector calculations is ±1 at the least
significant digit.
• If a vector calculation result is too large to fit into Vector Answer Memory, an error occurs.
• You can use the following operation to transfer Vector Answer Memory contents to another
vector.
VctAns → Vct

In the above,  is any variable name A through Z. The above does not affect the contents of
Vector Answer Memory.
• Vector memory and matrix memory are compatible with each other, so vector memory
contents can be assigned to matrix memory, if you want.
Vct
 → Mat 
In the above,  and  are any variable names A through Z.
u Vector Data Input Format [OPTN]-[MAT]-[Vct]
The following shows the format you should use when inputting data to create a vector using
the Vct command.
→ Vct [A to Z] [a

] → Vct [A to Z]
Example To input the following data to Vct A: [ 1 2 3 ]
!+( [ )!+( [ )b,c,d
!-( ] )!-( ] )a
K2(MAT)6(g)6(g)1(Vct)

Vector name
• The maximum value of both m and n is 999.
• An error occurs if memory becomes full as you are inputting data.
• You can also use the above format inside a program that inputs vector data.
All of the following examples assume that vector data is already stored in memory.
