More precisely, if dij is the ijth entry of a diagonal matrix D, then dij = 0 unless i = j. Such matrices look like the following. D = [ ∗ 0 ⋱ 0 ∗] where ∗ is a number which might not be zero.

WebSince A is invertible, then = 0 is not an eigenvalue of A; so that all of the diagonal entries of D are nonzero, and so D is also invertible. Therefore, A 1 = P 1 1 D 1P 1 = PD 1P 1; and A 1 is also diagonalizable with the same diagonalizing matrix P; and the diagonal matrix is made up of the inverses of the eigenvalues of A: Question 3.

Webiare the diagonal entries. A linear transformation, T: Rn!Rn, is diagonalizable if there is a basis Bof Rnso that [T] Bis diagonal. This means [T] is similar to the diagonal matrix [T] B. Similarly, a matrix A2R nis diagonalizable if it is similar to some diagonal matrix D. To diagonalize a linear transformation is to nd a basis Bso that [T ... In linear algebra, a diagonal matrix is a matrix in which the entries outside the main diagonal are all zero; the term usually refers to square matrices. Elements of the main diagonal can either be zero or nonzero. An example of a 2×2 diagonal matrix is , while an example of a 3×3 diagonal matrix is. An identity matrix of any size, or any multiple of it (a scalar matrix), is a diagonal matrix.
