WebA diagonal matrix is a matrix that is both upper triangular and lower triangular. i.e., all the elements above and below the principal diagonal are zeros and hence the name "diagonal matrix". Its mathematical definition is, a matrix A = [a ij] is said to be diagonal if A is a square matrix aij = 0 when i ≠ j. WebNow suppose AC = CD, and the matrix C is invertible. Then we can write D = C 1AC. And so we can think of the matrix C as converting A into a diagonal matrix. Definition 14.3.
