Syntax

XMVECTOR&  operator -=(
  [ref] XMVECTOR &V1,
        XMVECTOR V2
);

Parameters

• V1 [ref]
  Reference to current instance of XMVECTOR.

• V2
  XMVECTOR instance whose components are to be subtracted from the components of V1.

Return value

Reference to the updated current instance of XMVECTOR.

Remarks

   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;
