operator*= function (directxmath.h)

Multiplies one XMVECTOR instance by a second instance, returning a reference to the updated initial instance.

The operator *= multiplies each component of the current instance of XMVECTOR Data Type by the corresponding component in a second specified instance of XMVECTOR, returning a reference to the updated initial instance.

Note  This operator is only available under C++.

Syntax

XMVECTOR &XM_CALLCONV operator*=(
  XMVECTOR & V1,
  FXMVECTOR  V2
) noexcept;

Parameters

V1

Reference to current instance of XMVECTOR.

V2

XMVECTOR instance whose components are to be multiplied against the corresponding elements of V1.

Return value

Reference to the updated current instance of XMVECTOR containing the result of the multiplication operation.

Remarks

The following pseudocode demonstrates the operation of this operator:

   XMVECTOR V1;
   XMVECTOR V2;
   V1.x = V1.x * V2.x;
   V1.y = V1.y * V2.y;
   V1.z = V1.z * V2.z;
   V1.w = V1.w * V2.w;
