## What Is the Rank of a Matrix?

In linear algebra, the concept of rank is a numerical value assigned to a matrix. It represents the maximum number of rows or columns in the matrix that are linearly independent. Essentially, it measures the "freedom" or "dimensionality" of the matrix.

To grasp the concept of rank, it's important to understand linear independence. Rows or columns in a matrix are considered linearly independent if none of them can be expressed as a linear combination of the others. The rank tells us how many of these independent rows or columns exist within the matrix.

In mathematical terms, let's consider a $m\times n$ matrix $A$. The rank of $A$, denoted as $\operatorname{rank}(A)$, can be determined by performing row operations to transform the matrix into its row-echelon form or reduced row-echelon form. The rank corresponds to the number of non-zero rows in the resulting matrix.

For example, consider the following matrix $A$:

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

To find the rank of the matrix $A$, we can perform row operations to obtain its row-echelon form:

$$R=\left[\begin{array}{ccc}1&2&3\\0&-3&-6\\0&0&0\end{array}\right]$$

In this case, there are two non-zero rows in the row-echelon form, so the rank of the matrix $A$ is $2$.

Understanding the rank of a matrix provides insights into its properties and relationships. It helps in solving systems of linear equations, determining the dimension of vector spaces, and analyzing the invertibility of matrices.
