    Scale Method (Coordinate2D)
    In This Topic
    Scales the Coordinate2D by the given factor.
    Syntax
    public void Scale( 
       double scaleFactor
    )
    Public Sub Scale( _
       ByVal scaleFactor As Double _
    ) 

    Parameters

    scaleFactor
    The factor by which to scale.
    Exceptions
    ExceptionDescription
    scaleFactor is NaN.
    Remarks
    Each component of the Coordinate2D is multiplied by scaleFactor. If the scale factor is positive, the direction is not changed. If the scale factor is negative, the direction is opposite the original direction. The Magnitude of the scaled Coordinate2D = original magnitude * Abs(scaleFactor).

    Scale

    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);
