The following example shows how to scale a Matrix structure.


private Matrix scaleExample()
{
    Matrix myMatrix = new Matrix(5, 10, 15, 20, 25, 30);

    // Scale myMatrix by a horizontal factor of 2 
    // and a vertical factor of 4 about the origin. 
    // After this operation, 
    // myMatrix is equal to (10, 40, 30, 80, 50, 120)
    myMatrix.Scale(2, 4);

    return myMatrix;

}

private Matrix scaleAboutPointExample()
{
    Matrix myMatrix = new Matrix(5, 10, 15, 20, 25, 30);

    // Scale myMatrix by a horizontal factor of 2 
    // and a vertical factor of 4 about the  
    // point (100,100). 
    // After this operation, 
    // myMatrix is equal to (10, 40, 30, 80, -50, -180)
    myMatrix.ScaleAt(2, 4, 100, 100);

    return myMatrix;

}
