Specific properties of the determinants make them useful for different applications like solving the linear system of equations, checking the invertibility of a matrix, finding the area and volume of geometric shapes, and so on. The determinant of a matrix \(A\) is denoted as \(det(A)\), \(det A\) or \(|A|\). The determinant of a matrix is a scalar value calculated from the elements of a Square Matrix (matrix with \(m = n\)). Block matrices whose off-diagonal blocks are all equal to zero are called block-diagonal because their structure is similar to that. A first result concerns block matrices of the form or where denotes an identity matrix, is a matrix whose entries are all zero and is a square matrix.
