| Vector Class |
The Vector class represents a D-dimensional Euclidean vector.
Vectors are immutable: their values cannot be changed after they are created.
It includes methods for addition, subtraction,
dot product, scalar product, unit vector, Euclidean norm, and the Euclidean
distance between two vectors.

SyntaxC#
public class Vector
The Vector type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | Vector(Double) |
Initializes a vector from either an array or a vararg list.
The vararg syntax supports a constructor that takes a variable number of
arugments such as Vector x = new Vector(1.0, 2.0, 3.0, 4.0). |
| Vector(Int32) | Initializes a d-dimensional zero vector. |
Properties| Name | Description | |
|---|---|---|
 | Dimension |
Returns the dimension of this vector. |
| Length |
Returns the length (dimenstion) of this vector. For better semantics, use Dimension |
Methods| Name | Description | |
|---|---|---|
| Cartesian |
Returns the ith cartesian coordinate. |
| Direction |
Returns a unit vector in the direction of this vector. |
| DistanceTo |
Returns the Euclidean distance between this vector and the specified vector. |
| Dot |
Returns the do product of this vector with the specified vector. |
| Magnitude |
Returns the magnitude of this vector.
This is also known as the L2 norm or the Euclidean norm. |
 | MainTest |
Demo test the Vector data type. |
| Minus |
Returns the difference between this vector and the specified vector. |
| Plus |
Returns the sum of this vector and the specified vector. |
| Scale |
Returns the scalar-vector product of this vector and the specified scalar |
| Times |
Returns the scalar-vector product of this vector and the specified scalar.
Use Scale(Double) for better semantics. |
| ToString |
Returns a string representation of this vector. (Overrides ObjectToString.) |
