// .NAME vtkMatrix4x4 - represent and manipulate 4x4 transformation matrices
// .SECTION Description
// vtkMatrix4x4 is a class to represent and manipulate 4x4 matrices.
// Specifically, it is designed to work on 4x4 transformation matrices
// found in 3D rendering using homogeneous coordinates [x y z w].
// .SECTION See Also
// vtkTransform

class VTK_COMMON_EXPORT vtkMatrix4x4 : public vtkObject
{
// Some of the methods in here have a corresponding static (class)
// method taking a pointer to 16 doubles that constitutes a user
// supplied matrix. This allows C++ clients to allocate double arrays
// on the stack and manipulate them using vtkMatrix4x4 methods.
// This is an alternative to allowing vtkMatrix4x4 instances to be
// created on the stack (which is frowned upon) or doing lots of
// temporary heap allocation within vtkTransform and vtkActor methods,
// which is inefficient.
