## What Is an Orthogonal Complement?

The orthogonal complement is an integral concept in linear algebra. Mathematically, if you have a vector space $V$ and a subspace $W$ within it, the orthogonal complement of $W$ in $V$, often denoted as $W^{\perp}$, comprises all vectors in $V$ that are orthogonal to every vector in $W$.

If $\mathbf{\vec{v}}$ is a vector in $V$ and $\mathbf{\vec{w}}$ is a vector in $W$, $\mathbf{\vec{v}}$ is orthogonal to $\mathbf{\vec{w}}$ if their dot product is zero. That is, $\mathbf{\vec{v}}\cdot\mathbf{\vec{w}}=0$. This is the defining characteristic of the orthogonal complement.

For example, consider $V$ in $\mathbb{R^3}$, and $W$ is the subspace spanned by the vector $\langle1,2,3\rangle$. The orthogonal complement $W^{\perp}$ includes all vectors in $\mathbb{R^3}$ that are orthogonal to $\langle1,2,3\rangle$. So any vector $\mathbf{\vec{v}}=\langle v_1,v_2,v_3\rangle$ in $W^{\perp}$ must satisfy:

$$\langle1,2,3\rangle\cdot\langle v_1,v_2,v_3\rangle=0$$

Or,

$$v_1+2v_2+3v_3=0$$

This equation characterizes all vectors in the orthogonal complement $W^{\perp}$.

The process of finding orthogonal complements is fundamental to many scientific and engineering disciplines, such as signal processing in physics and machine learning in computer science.

#### What is the orthogonal complement?

The orthogonal complement is a set or space of vectors that are perpendicular (orthogonal) to a given vector or subspace within a larger space. Essentially, if you have a subspace $W$ in a larger space $V$, the orthogonal complement of $W$ comprises all vectors in $V$ that are orthogonal to every vector in $W$.
