Public Member Functions
	Matrix4 ()
	Default constructor; initializes the matrix to an identity transform.

	Matrix4 (double e11, double e12, double e13, double e14, double e21, double e22, double e23, double e24, double e31, double e32, double e33, double e34, double e41, double e42, double e43, double e44)
	This constructor allows you to initialize the matrix as you please.

	Matrix4 (const double *m)
	Initializes the matrix from an array of 16 double-precision values (row-major).

	~Matrix4 ()
	Destructor.

double TRITONAPI	operator() (int x, int y) const
	Retrieve a specific matrix element.

void TRITONAPI	ToFloatArray (float val[16]) const
	Populates a static array of 16 floats with the contents of the matrix.

Matrix4 TRITONAPI	operator* (const Matrix4 &mat) const
	Multiplies two matrices together.

Vector4 TRITONAPI	operator* (const Vector4 &vec) const
	Transform a point by the matrix.

Vector3 TRITONAPI	operator* (const Vector3 &vec) const
	Transform a point by the matrix.

void TRITONAPI	Transpose ()
	Transposes the matrix in-place.

Matrix4 TRITONAPI	InverseCramers (double epsilon=1E-12) const
	Computes the inverse of the matrix using Cramer's rule.

double *TRITONAPI	GetRow (int row) const
	Retrieves a pointer into the requested row of the matrix.

Public Attributes
double	elem [4][4]
	Data members are public for convenience.

Friends
Vector4 TRITONAPI	operator* (const Vector4 &vec, const Matrix4 &mat)
	Multiplies a 1x3 vector by a matrix, yielding a 1x3 vector.
