@sorainsm Can you please explain the relationship between Dot Product of two n-dimensional vectors( DD1 ) and AB1, AB2? Base on the description of AB1 and AB2, I think it states that this library is only considering the 3 dimensions(3D) problems. Please correct me if I wrong.

Therefore, is it means that in the equation of DD1, the n-dimensional vectors where "n" is at most 3?

@sharyuwu, I believe that @sorainsm is using DD1 to specify the general concept of dot product. This concept applies to n-dimensional vectors. The more general way of writing this is better than specifying 3 dimensional vectors, because someone else can reuse this definition in their document.
