XMMATRIX::operator* function (directxmath.h)

  • Article

Performs a matrix multiplication of the current instance of XMMATRIX by another instance of XMMATRIX.

This operator performs a matrix multiplication of the current instance of XMMATRIX by another instance of XMMATRIX.

Note  This operator is only available when developing with C++.
 

Syntax

C++ 
XMMATRIX XM_CALLCONV operator*(
  [ref] FXMMATRIX M
) noexcept;

Parameters

[ref] M

Instance of XMMATRIX to be multiplied against the current instance of XMMATRIX.

Return value

An instance of XMMATRIX containing the result of the matrix multiplication.

Remarks

The current XMMATRIX is the left hand side of the matrix multiplication. That is the matrix operation mat2 = mat1 * M can be implemented as:

      XMMATRIX mat1;
      XMMATRIX mat2;
      XMMATRIX M
      mat2 = mat1 * M
 
      const XMMATRIX& M;
      XMMATRIX& mat1;
      XMMATRIX& mat2;
      mat2 = XMMatrixMultiply(mat1, M);
