upper triangular matrix
Translation of "upper triangular matrix" in Chinese
上三角矩阵
A more precise statement is given by the Jordan normal form theorem, which states that in this situation, A is similar to an upper triangular matrix of a very particular form.
一个更进一步的结论是由若尔当标准形定理得出，说明了A实际上相似于一个十分特别的上三角矩阵（若尔当形）。
The transpose of an upper triangular matrix is a lower triangular matrix and vice versa.
In mathematics, the Iwasawa decomposition (aka KAN from its expression) of a semisimple Lie group generalises the way a square real matrix can be written as a product of an orthogonal matrix and an upper triangular matrix (a consequence of Gram-Schmidt orthogonalization).
数学中，半单李群的岩泽分解 KAN 推广了实方阵能写成一个正交矩阵和上三角矩阵的乘积（格拉姆-施密特正交化之推论）。
A fast algorithm for the upper triangular matrix R of QR Decomposition of T. (which is m×n block - Toeplitz matrix with r×s rectangular blocks)and R-T both using only O (mnrs) multiplication is presented. where we get E and R-T computing the Cholesky factor R of TTT.
对块数为m×n阶数为mr×ns的块－Toeplitz矩阵T提出一种通过T的Cholesky因于R来求T的QR分解中上三角矩阵R及R－T的快速算法，计算量为O（mnrs2）。
Similarly, the QR decomposition expresses A as QR with Q an orthogonal matrix and R an upper triangular matrix.
這種方式，把矩阵 分解成一个半正交矩阵 与一个上三角矩阵 的积。
