Luna::Simd::matmul_f3x3

float3x4 matmul_f3x3(float3x4 a, float3x4 b)

Performs 3x3 matrix multiplication on a and b, and stores the result in dst.

dst[0].x := a[0].x * b[0].x + a[0].y * b[1].x + a[0].z * b[2].x
dst[0].y := a[0].x * b[0].y + a[0].y * b[1].y + a[0].z * b[2].y
dst[0].z := a[0].x * b[0].z + a[0].y * b[1].z + a[0].z * b[2].z
dst[1].x := a[1].x * b[0].x + a[1].y * b[1].x + a[1].z * b[2].x
dst[1].y := a[1].x * b[0].y + a[1].y * b[1].y + a[1].z * b[2].y
dst[1].z := a[1].x * b[0].z + a[1].y * b[1].z + a[1].z * b[2].z
dst[2].x := a[2].x * b[0].x + a[2].y * b[1].x + a[2].z * b[2].x
dst[2].y := a[2].x * b[0].y + a[2].y * b[1].y + a[2].z * b[2].y
dst[2].z := a[2].x * b[0].z + a[2].y * b[1].z + a[2].z * b[2].z

The forth element of every row of dst is indefinite.
