Being one of the fundamentals of algebra, it is essential for every aspirant to have clear concepts and sufficient practice. The elements in a square matrix for which the number of the row is equal to the number of the column is called the leading diagonal or the principle diagonal of the matrix. A square matrix is called idempotent if the product of the matrix with itself results in the same matrix.
