In This Topic
    Subtraction Operator (Coordinate2D)
    In This Topic
    Constructs a new Coordinate2D by subtracting two Coordinate2D objects. Vector subtraction is used.
    Syntax
    public Coordinate2D operator -( 
       Coordinate2D a,
       Coordinate2D b
    )
    Public Operator -( _
       ByVal a As Coordinate2D, _
       ByVal b As Coordinate2D _
    ) As Coordinate2D

    Parameters

    a
    b

    Return Value

    A newly constructed Coordinate2D by subtracting the components of the two Coordinate2D objects from each other.
    Example
    2D Vector Operations
    Coordinate2D v = new Coordinate2D(0, 1);
    // v.Magnitude = 1
    
    Coordinate2D other = new Coordinate2D(-1, 0);
    double dotProduct = v.DotProduct(other);
    // dotProduct = 0
    
    Coordinate2D w = v + other;
    // w = (-1, 1)
    
    w += other;
    // w = (-2, 1)
    
    w -= other;
    // w = (-1, 1)
    
    w = v;
    w.Rotate(Math.PI, other);
    // w = (-2, -1)
    
    w = other;
    
    w.Scale(-4);
    // w = (4, 0)
    // w.Magnitude = 4
    
    w.Move(-1, 4);
    // w = (3, 4)
    // w.Magnitude = 5
    
    w.Move(-6, -1);
    Tuple<double, double> components = w.QueryComponents();
    // components = (-3, 3)
    // w.Magnitude = 3 * Math.Sqrt(2)
    
    Coordinate2D unitVector = w.GetUnitVector();
    // w = (-Math.Sqrt(2) / 2, Math.Sqrt(2) / 2)
    // w.Magnitude = 1
    
    
    w.SetComponents(3, 4);
