Determining the rank of a matrix is a crucial step in matrix analysis, particularly when dealing with square matrices. The process begins by calculating the determinant of the matrix.

If the determinant of the matrix is not equal to zero, it indicates that the matrix is invertible and has full rank. In this case, the rank of the matrix is equal to its order, n.

However, if the determinant is zero, it means that the matrix is singular and does not have full rank. To determine the exact rank, further analysis is required.

One approach to finding the rank of a singular matrix is to examine its minors. A minor of a matrix is the determinant of a smaller matrix formed by deleting certain rows and columns from the original matrix.

Specifically, we look for a non-zero minor of order n-1. If such a minor exists, it implies that the matrix has a rank of n-1. This is because the presence of a non-zero minor of order n-1 indicates that the matrix has at least n-1 linearly independent rows (or columns).
