两个向量之间的角度matlab [英] Angle between two vectors matlab

问题描述

我想计算两个向量V = [Vx Vy Vz] 和B = [Bx By Bz] 之间的角度.这个公式对吗?

I want to calculate the angle between 2 vectors V = [Vx Vy Vz] and B = [Bx By Bz]. is this formula correct?

VdotB = (Vx*Bx + Vy*By + Vz*Bz)

 Angle = acosd (VdotB / norm(V)*norm(B))

还有其他方法可以计算吗?

and is there any other way to calculate it?

我的问题不是标准化向量或使其更容易.我在问如何获得这两个向量之间的角度

My question is not for normalizing the vectors or make it easier. I am asking about how to get the angle between this two vectors

推荐答案

基于这个链接，这似乎成为最稳定的解决方案:

Based on this link, this seems to be the most stable solution:

atan2(norm(cross(a,b)), dot(a,b))
