Similarly a strictly lower triangular matrix is a lower triangular matrix which has 0 on the main diagonal. See for instance page 3 of these lecture notes by Garth Isaak, which also shows the block-diagonal trick (in the upper- instead of lower-triangular setting). 0000007976 00000 n The Jordan diagram of A (for 0) is denoted by J(A). Using the diagonalization, we find the power of the matrix. 378 0 obj << /Linearized 1 /O 381 /H [ 1182 518 ] /L 630809 /E 58677 /N 13 /T 623130 >> endobj xref 378 29 0000000016 00000 n 0000001678 00000 n 0000007187 00000 n �q_5��}� �a�:my86\ p��'m�iuK��p�%�Ux�� ٭��@��;�F� фgj��5��9��l|�`� 2�-�L�̖��#'�%L�Z��zul�ɒ��$QJMl1>��9�2z;�` L�9� endstream endobj 393 0 obj << /Type /Font /Subtype /TrueType /Name /F3 /BaseFont /TimesNewRoman,Italic /Encoding /WinAnsiEncoding >> endobj 394 0 obj 676 endobj 395 0 obj << /Filter /FlateDecode /Length 394 0 R >> stream 0000005496 00000 n 1.3.13b: A matrix is nilpotent if Ak = 0 for some k. A matrix A is strictly upper triangular if Aij = 0 for i ‚ j. i.e. By the LU decomposition algorithm, an invertible matrix may be written as the product of a lower triangular matrix L by an upper triangular matrix U if and only if all its leading principal minors are non-zero. Of course, the same trick works for extracting the strictly upper triangular portion of a matrix: just pass the transpose of the matrix to the StrictLowerTriangular function. When you multiply a strictly upper triangular matrix by itself, the non-zero entries shift one up and to the right, further from the leading diagonal.

We will call the transformation S-1AS of a matrix A for a nondegenerate lower triangular matrix S an admissible transformation of A. Therefore, a square matrix which has zero entries below the main diagonal, are the upper triangular matrix and a square matrix which has zero entries above the main diagonal of the matrix is considered as lower triangular one. We diagonalize a given 2 by 2 upper triangular matrix by finding its eigenvalues and eigenvectors.
