XMVectorMultiplyAdd method

Computes the product of the first two vectors added to the third vector.

Syntax


XMVECTOR XMVectorMultiplyAdd(
  [in]  XMVECTOR V1,
  [in]  XMVECTOR V2,
  [in]  XMVECTOR V3
);

Parameters

V1 [in]

Vector multiplier.

V2 [in]

Vector multiplicand.

V3 [in]

Vector addend.

Return value

Returns the product-sum of the vectors.

Remarks

The following pseudocode demonstrates the operation of the function:


XMVECTOR Result;

Result.x = V1.x * V2.x + V3.x;
Result.y = V1.y * V2.y+ V3.y;
Result.z = V1.z * V2.z+ V3.z;
Result.w = V1.w * V2.w+ V3.w;

return Result;

Platform Requirements
