5.2.3 Triangular matrices and algebra of triangular matrices A matrix with all elements under/above the main diagonal equal to zero is called an upper/lower triangular matrix. A unit triangular matrix is triangular matrix with 1s on the main diagonal. There are a few useful properties about pro...

简介:上三角矩阵(Upper Triangular Matrix)是一种特殊形式的矩阵,其非零元素仅位于主对角线以上。在数学和工程领域中,上三角矩阵通常用于线性代数和微积分等问题。以下是一些关于上三角矩阵的特点和应用: 上三角矩阵(Upper Triangular Matrix)是一种特殊形式的矩阵,其非零元素仅位于主对角线以上。在数学和工程领域中,...
The second row is the number of elements in the strict upper triangle of an nxn matrix (as well as the strict lower triangle.) The point being that you CANNOT supply a vector of length n and hope to get the result that you are asking for. It just won't work, ever, except for n...

As is well known, there exists an invertible matrix S such that S-1AS is upper triangular. The present paper is concerned with the observation that S can always be chosen in the form S=∏L, where ∏ is a permutation matrix and L is lower triangular. Assuming that the eigenvalues of A...
