strictly diagonally dominant matrix

基本解釋

The estimation on the inverse elements of strictly diagonally dominant tridiagonal matrix is established; in this estimation, the nonnegative condition of matrix elements is moved.
利用嚴(yán)格對角占優(yōu)和三對角矩陣的某些特性，推導(dǎo)出嚴(yán)格對角占優(yōu)三對角矩陣逆元素的統(tǒng)一估計(jì)式。
In this paper we propose the concept of a weak strictly diagonally dominant matrix given some de terminate sufficient conditions for generalized strictly diagonally dominant matrices.
本文提出了弱嚴(yán)格對角占優(yōu)矩陣的概念，并由此給出了廣義嚴(yán)格對角占優(yōu)矩陣的若干判定條件。
In this paper, some sufficient conditions and a necessary condition for a matrix to be a generalized strictly diagonally dominant matrix is given. Some previous results are improved and generalized.
本文給出了廣義嚴(yán)格對角占優(yōu)矩陣的若干充分條件和必要條件，從而改進(jìn)和推廣了一些已有的結(jié)果。
