## What Is a Column Space?

In the realm of linear algebra, the column space of a matrix, also known as the range of a matrix, is one of the four fundamental subspaces that give us insights into the solutions of linear systems. It consists of all possible linear combinations of the column vectors of the matrix.

Mathematically, let's suppose we have a matrix $A$ whose columns are represented by the vectors $\left\{\mathbf{\vec{a_1}},\mathbf{\vec{a_2}},\dots,\mathbf{\vec{a_n}}\right\}$. The column space of $A$, denoted by $\operatorname{col}(A)$, consists of vectors that can be formed by multiplying each column vector by some scalar and adding them together. This can be expressed in the following way:

$$\operatorname{col}(A)=\left\{x_1\mathbf{\vec{a_1}}+x_2\mathbf{\vec{a_2}}+\dots+a_n\mathbf{\vec{a_n}}\mid x_1,x_2,\ldots,x_n\in\mathbb{R}\right\}$$

Here, $x_1,x_2,\ldots,x_n$ are scalars and they belong to the set of all real numbers, denoted by $\mathbb{R}$. The scalars can be any real number, and different scalars will yield different vectors in the column space.

Let's take an example to understand this better. Suppose we have the following 3x3 matrix $B$:

$$B=\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]$$

The column vectors are $\langle1,4,7\rangle$, $\langle2,5,8\rangle$, and $\langle3,6,9\rangle$. The column space of $B$ will be the set of all possible vectors we can get by taking any real numbers $x_1$, $x_2$, and $x_3$, and computing the vector $x_1\cdot\langle1,4,7\rangle+x_2\cdot\langle2,5,8\rangle+x_3\cdot\langle3,6,9\rangle$.

The column space of a matrix plays a key role in determining the solution of the system of linear equations that the matrix represents. By understanding the column space, we gain critical insights into the structure of the solution of the system.
