D3DXMatrixInverse function (D3dx9math.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Calculates the inverse of a matrix.
Syntax
D3DXMATRIX* D3DXMatrixInverse(
_Inout_ D3DXMATRIX *pOut,
_Inout_ FLOAT *pDeterminant,
_In_ const D3DXMATRIX *pM
);
Parameters
-
pOut [in, out]
-
Type: D3DXMATRIX*
Pointer to the D3DXMATRIX structure that is the result of the operation.
-
pDeterminant [in, out]
-
Type: FLOAT*
Pointer to a FLOAT value containing the determinant of the matrix. If the determinant is not needed, set this parameter to NULL.
-
pM [in]
-
Type: const D3DXMATRIX*
Pointer to the source D3DXMATRIX structure.
Return value
Type: D3DXMATRIX*
Pointer to a D3DXMATRIX structure that is the inverse of the matrix. If matrix inversion fails, NULL is returned.
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixInverse function can be used as a parameter for another function.
