linear algebra - Diagonalization of triangular matrices

The transpose of an upper triangular matrix is a lower triangular matrix and vice versa. A matrix which is both symmetric and triangular is diagonal. In a similar vein, a matrix which is both normal (meaning A A = AA , where A is the conjugate transpose) and triangular is also diagonal. This can be seen by looking at the diagonal entries of A A and AA . The determinant and permanent of a triangular matrix equal the product of the diagonal entries, a… WebMar 20, 2024 · Triangular Matrix Properties. The transpose of a triangular matrix is triangular. The transpose of a lower triangular matrix is an upper triangular matrix and … WebProperties of triangular matrices: An \(n \times n\) triangular matrix has \(n(n-1)/2\)entries that must be zero, and \(n(n+1)/2\)entries that are allowed to be non-zero. Zero matrices, identity matrices, and diagonal matrices are all both lower triangular and upper triangular. Permutation Matrices artesan slp

WebThat is, there is an invertible matrix B such that: 0 = B A B − 1. Then A = B − 1 0 B = 0. A little more directly, you can see the eigenvalues of A are all 0 because A − x I is upper triangular with x 's down the diagonal. Therefore the characteristic polynomial is x n for some n.

WebIf Ais upper-triangular or lower-triangular, then det(A)is the product of its diagonal entries. Proof Suppose that Ahas a zero row. Let Bbe the matrix obtained by negating the zero row. Then det(A)=−det(B)by the second defining property. But A=B,so det(A)=det(B): E123000789FR2=−R2−−−−→E123000789F. WebSep 17, 2024 · We know that the determinant of a triangular matrix is the product of the diagonal elements. Therefore, given a matrix A, we can find P such that P − 1AP is upper triangular with the eigenvalues of A on the diagonal. Thus det(P − 1AP) is the product of the eigenvalues. Using Theorem 3.4.3, we know that det(P − 1AP) = det(P − 1PA) = det(A).
