XMLoadFloat4x4A function (directxmath.h)

Loads an XMFLOAT4X4A into an XMVECTOR.


XMMATRIX XM_CALLCONV  noexcept XMLoadFloat4x4A(
  [in] const XMFLOAT4X4A *pSource


[in] pSource

Address of the XMFLOAT4X4A structure to load.

Return value

Returns an XMMATRIX loaded with the data from the pSource parameter.


XMFLOAT4X4A is a row-major form of the matrix. This function could be used to read column-major data, but would then need to be transposed with XMMatrixTranpose before use in other XMMATRIX functions.

The members of the XMFLOAT4X4A structure (_11, _12, _13, and so on) are loaded into the corresponding members of the XMMATRIX.

Platform Requirements
