u Vector Addition, Subtraction, and Multiplication [OPTN]-[MAT/VCT]-[Vct]

Example 1 To determine the sum of the two vectors shown below (Vct A + Vct B):

Vct A = [ 1 2 ] Vct B = [ 3 4 ]

K2(MAT/VCT)6(g)6(g)1(Vct)

av(A)+1(Vct)al(B)w

Example 2 To determine the product of the two vectors shown below (Vct A × Vct B):

Vct A = [ 1 2 ] Vct B =

K2(MAT/VCT)6(g)6(g)1(Vct)

av(A)*1(Vct)al(B)w

Example 3 To determine the product of the matrix and vector shown below (Mat A ×

Vct B):

Mat A = Vct B =

K2(MAT/VCT)1(Mat)

av(A)*6(g)6(g)

1(Vct)al(B)w

• When performing addition or subtraction of two vectors, they both must have the same

dimensions.

• When multiplying Vct A (1 ×

n) and Vct B (m × 1), n and m must be the same.

u Dot Product [OPTN]-[MAT/VCT]-[DotP]

Example To determine the dot product of the two vectors below

Vct A = [ 1 2 ] Vct B = [ 3 4 ]

K2(MAT/VCT)6(g)6(g)

2(DotP( )1(Vct)av(A),

1(Vct)al(B))w
