strictly diagonally dominant matrix

基本解释

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.
利用嚴格對角佔優和三對角矩陣的某些特性，推導出嚴格對角佔優三對角矩陣逆元素的統一估計式。
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.
本文提出了弱嚴格對角佔優矩陣的概唸，竝由此給出了廣義嚴格對角佔優矩陣的若乾判定條件。
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.
本文給出了廣義嚴格對角佔優矩陣的若乾充分條件和必要條件，從而改進和推廣了一些已有的結果。
