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

Vct B):

Mat A = Vct B =

K2(MAT)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]-[DotP]

Example To determine the dot product of the two vectors below

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

K2(MAT)6(g)6(g)

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

1(Vct)al(B))w

u Cross Product [OPTN]-[MAT]-[CrsP]

Example To determine the cross product of the two vectors below

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

K2(MAT)6(g)6(g)

3(CrsP)1(Vct)av(A),

1(Vct)al(B))w

u Angle Formed by Two Vectors [OPTN]-[MAT]-[Angle]

Example To determine the angle formed by two vectors

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

K2(MAT)6(g)6(g)

4(Angle)1(Vct)av(A),
