Orthogonal complement - Wikipedia
In the mathematical fields of linear algebra and functional analysis, the orthogonal complement of a subspace of a vector space equipped with a bilinear form is the set of all vectors in that are orthogonal to every vector in .

正交子空间 Orthogonal subspaces; 子空间S与子空间T正交，则S中的任意一个向量都和T中的任意向量正交。黑板所在的平面和地板所在平面不是 正交关系 ，沿两者的交线方向的向量同时属于两个平面，但并不与自己正交。 我们在平面内讨论正交子空间，平面的子空间包
In this lecture we learn what it means for vectors, bases and subspaces to be orthogonal. The symbol for this is ⊥. The “big picture” of this course is that the row space of a matrix’ is orthog onal to its nullspace, and its column space is orthogonal to its left nullspace. Orthogonal is just another word for perpendicular.

2022年9月17日 · Learn to compute the orthogonal complement of a subspace. Recipes: shortcuts for computing the orthogonal complements of common subspaces. Picture: orthogonal complements in \(\mathbb{R}^2 \) and \(\mathbb{R}^3 \).
What is the difference between orthogonal subspaces and orthogonal …
2017年6月7日 · Given an inner product space $(\Bbb V, \,\cdot\,)$, two vector spaces $X, Y \leq \Bbb V$ of are orthogonal (we denote $X \perp Y$) iff every element of $X$ is orthogonal to every element of $Y$. If $X$ and $Y$ are orthogonal and complementary, they …
The orthogonal complement of S, denoted S⊥, is the set of all vectors x ∈ Rn that are orthogonal to S. That is, S⊥ is the largest subset of Rn orthogonal to S. Theorem 1 S⊥ is a subspace of Rn. Note that S ⊂ (S⊥)⊥, hence Span(S) ⊂ (S⊥)⊥. Theorem 2 (S⊥)⊥ = Span(S). In particular, for any subspace V we have (V⊥)⊥ = V ...

Orthogonal Subspaces -- from Wolfram MathWorld
2025年1月14日 · Two subspaces S_1 and S_2 of R^n are said to be orthogonal if the dot product v_1·v_2=0 for all vectors v_1 in S_1 and all v_2 in S_2.
Let 𝑺 be a subspace of 𝒏 ‐dimensional vector space 𝑽 . A vector 𝝁 in 𝑽 is orthogonal to 𝑺 if 𝝁 is orthogonal to every vector in 𝑺. The set of all vectors 𝝁 orthogonal to 𝑺 is called the orthogonal complement of 𝑺 in 𝑽 and is denoted by 𝑺 D.
