Module 7: Vector Operations (Inner & Cross Products)

dot(u, v)

Computes the dot product of vectors u and v.

norm(v)

Computes the norm (length/magnitude) of vector v.

norm(u - v)

Computes the distance between the two vectors u and v.

u / norm(u)

Creates a unit vector in the same direction as u.

acos(x)

Arccosine; computes the inverse cosine in radians.

acosd(x)

Arccosine (degrees); computes the inverse cosine in degrees.

cross(u, v)

Computes the cross product of 3D vectors u and v.

norm(cross(u, v))

Computes the area of the parallelogram defined by u and v.
