XMMatrixInverse method

Computes the inverse of a matrix.

Syntax


XMMATRIX XMMatrixInverse(
  [out, optional] XMVECTOR *pDeterminant,
  [in]            XMMATRIX M
);

Parameters

pDeterminant [out, optional]: Address of a vector, each of whose components is the determinant of M. This parameter can be a nullptr.
M [in]: Matrix to invert.

Return value

Returns the matrix inverse of M. If there is no inverse (that is, if the determinant is 0), XMMatrixInverse returns an infinite matrix.

Remarks

Note For XNAMATH version 2.04 and earlier, the pDeterminant parameter isn't optional. That is, for XNAMATH version 2.04 and earlier, you can't set pDeterminant to a nullptr.

Platform Requirements

Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
