Calculates the inverse of a matrix.

Syntax

D3DXMATRIX *D3DXMatrixInverse(

D3DXMATRIX *pOut, FLOAT *pDeterminant, CONST D3DXMATRIX *pM);

Parameters

pOut- [in, out] Pointer to the D3DXMATRIX structure that is the result of the operation.
pDeterminant- [in, out] Pointer to a
FLOATvalue containing the determinant of the matrix. If the determinant is not needed, set this parameter to NULL.pM- [in] Pointer to the source
D3DXMATRIXstructure.

Return Value

Pointer to a

D3DXMATRIXstructure 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

pOutparameter. In this way, theD3DXMatrixInversefunction can be used as a parameter for another function.
