vector3 class

vector3

The vector3 class defines a 3-dimensional vector. Several calculations between vector3 instances are defined. The constructor of vector3 requires an (x, y, z) coordinate.

Constructor

vector3(const double x, const double y, const double z)

Create a vector3 instance from a coordinate.

x

x-coordinate.

y

y-coordinate.

z

z-coordinate.

Functions

const double
inner_product(const vector3& v) const

Calculate an inner product with another vector3 instance v.

v

a vector3 instance.

const vector3
outer_product(const vector3& v) const

Calculate an outer product with another vectore instance v.

v

a vector3 instance.

const double
separation_cosine(const vector3& v) const

Calculate cosθ, where θ is the separation angle between another vector3 instance v.

v

a vector3 instance.

const angle
separation(const vector3& v) const

Calculate θ, where θ is the separation angle between another vector3 instance v.

v

a vector3 instance.

void
print() const

Write down the (x,y,z) coordinate in stdout.

Attributes

x

(double) x-coordinate.

y

(double) y-coordinate.

z

(double) z-coordinate.

d

(double) length of the vector.
