D3DXMatrixInverse function

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.
