DESCRIPTION
     A field containing a transformation matrix (an SbMatrix).

     SoSFMatrices are written to file as 16 floating point numbers separated
     by whitespace. For example, an identity matrix is written as:

	  1 0 0 0  0 1 0 0  0 0 1 0  0 0 0 1

FUNCTIONS
     void		 SoSMatrixSetMx(SoSMatrix *this, float a11, float a12,
			      float a13, float a14, float a21, float a22,
			      float a23, float a24, float a31, float a32,
			      float a33, float a34, float a41, float a42,
			      float a43, float a44)
	  Sets this field to contain the matrix given by the 16 values. For a
	  translation matrix, the x, y and z translations should be in the
	  a41, a42, and a43 arguments.

     SoType		 SoSMatrixGetClassTypeId()
     void		 SoSMatrixGetTypeId(const SoSMatrix *this)
	  Returns the type for this class or a particular object of this
	  class.

     const SbMatrix *	 SoSMatrixGet(const SoSMatrix *this)
	  Returns this field's value.

     void		 SoSMatrixSet(SoSMatrix *this, const SbMatrix *
			      newValue)
	  Sets this field to newValue.

     int		 SoSMatrixIsEq(const SoSMatrix *this, const SoSFMatrix
			      *f)
     int		 SoSMatrixIsNEq(const SoSMatrix *this, const
			      SoSFMatrix *f)
	  Returns TRUE if f is of the same type and has the same value as this
	  field.
