Question

Give one example of Diagonal matrix.

Answer 1

is a tridiagonal matrix. The main diagonal of a matrix consists of those elements where the row and column are equal. For matrix the main diagonal corresponds to the locations of the 1's. There are 2 other diagonals in this matrix. The diagonal corresponding to the 2's is called the subdiagonal, since it is below and once-removed from the main diagonal. Similarly, the diagonal corresponding to the 3's is the superdiagonal.
