This structure supplies the following operator overloads and type casts for D3DXMATRIX structures.

#ifdef __cplusplus
typedef struct D3DXMATRIX : public D3DMATRIX
{
public:

  D3DXMATRIX( CONST FLOAT * );
  D3DXMATRIX( CONST D3DMATRIX& );

 FLOAT _21, FLOAT _22, FLOAT _23, FLOAT _24,
 FLOAT _31, FLOAT _32, FLOAT _33, FLOAT _34,
 FLOAT _41, FLOAT _42, FLOAT _43, FLOAT _44 );


  // access grants
  FLOAT& operator () ( UINT Row, UINT Col );
  FLOAT  operator () ( UINT Row, UINT Col ) const;

  // casting operators
  operator FLOAT* ();
  operator CONST FLOAT* () const;

  // assignment operators
  D3DXMATRIX& operator *= ( CONST D3DXMATRIX& );
  D3DXMATRIX& operator += ( CONST D3DXMATRIX& );
  D3DXMATRIX& operator -= ( CONST D3DXMATRIX& );
  D3DXMATRIX& operator *= ( FLOAT );
  D3DXMATRIX& operator /= ( FLOAT );

  // unary operators
  D3DXMATRIX operator + () const;
