VEC_MultSubtract

C Specification

#include <nitro/fx/fx_vec.h>

void VEC_MultSubtract(
fx32 a,
const VecFx32* v1,
const VecFx32* v2,
VecFx32* pDest
);

Arguments

a An fx32 type scalar value.
v1   The pointer to a vector.
v2   The pointer to a vector.
pDest   The pointer to the vector where the result is stored.

Return Values

None.

Description

This function multiplies a VecFx32 type vector by a scalar value and then subtracts another vector from the product. The result is shown by *pDest = a x *v1 - *v2. v1, v2, and pDst can be pointers to the same vector.
