D3DXMATRIX

The D3DXMATRIX structure describes a matrix.

typedef struct D3DXMATRIX {
  union
  {
    float m[4][4];
  };
} D3DXMATRIX;

Remarks

In Direct3DX, the m23 element of a projection matrix cannot be a negative number. If your application needs to use a negative value in this location, it should scale the entire projection matrix by -1, instead.

C++ programmers can take advantage of operator overloading and type casting. The C++ implementation of the D3DXMATRIX structure implements overloaded constructors and overloaded assignment, unary, and binary (including equality) operators. For more information, see C++ Specific Features.
