正交 Orthogonality
(重定向自Orthogonal vectors)


![Orthogonality and rotation of coordinate systems compared between left: Euclidean space through circular angle ϕ, right: in Minkowski spacetime through hyperbolic angle ϕ (red lines labelled c denote the worldlines of a light signal, a vector is orthogonal to itself if it lies on this line).[5]](/uploads/202501/31/Orthogonality_and_rotation.svg5846.png)

正交是线性代数的概念,是垂直这一直观概念的推广。作为一个形容词,只有在一个确定的内积空间中才有意义。若内积空间中两矢量的内积为0,则称它们是正交的。如果能够定义矢量间的夹角,则正交可以直观的理解为垂直。物理中:运动的独立性,也可以用正交来解释。

Orthogonality 正交(重定向自Orthogonal vectors)
![]() ![]() ![]() ![]() In mathematics, orthogonality is the relation of two lines at right angles to one another (perpendicularity), and the generalization of this relation into n dimensions; and to a variety of mathematical relations thought of as describing non-overlapping, uncorrelated, or independent objects of some kind. |
