Is identity matrix a triangular matrix
WitrynaObserve that a scalar matrix is an identity matrix when k = 1. But every identity matrix is clearly a scalar matrix. 9) Upper Triangular Matrix. A square matrix in which all the elements below the diagonal are zero is known as the upper triangular matrix. For example, $$ A =\begin{bmatrix} 3 & -5 & 7\\ 0 & 4 & 0\\ 0 & 0 & 9 \end{bmatrix}$$ WitrynaTAalso equals the identity matrix, we have d i = 1 )d i = 1 . 5. A matrix is strictly upper triangular if it is upper triangular with zero diagonal el-ements. Show that if Ais an n nstrictly upper triangular matrix, then An = 0. We prove that for 1 k n, the diagonal and the rst (k 1) super-diagonals of Ak have only zero elements, i.e., (Ak)
