The IDirect3DDevice::SetMatrix method applies a matrix to a matrix handle. This matrix handle must have been created by using the IDirect3DDevice::CreateMatrix method.

D3DMATRIXHANDLE d3dMatHandle,
LPD3DMATRIX lpD3DMatrix
);
Parameters
d3dMatHandle
Matrix handle to be set.
lpD3DMatrix
Address of a D3DMATRIX structure that describes the matrix to be set.
Return Values
