摘要
在假设A∈Rn×n是一个L-矩阵,且A不是对角矩阵的前提下,给出了矩阵A为拟具非零元素链对角占优矩阵时的若干性质,并举例说明了具非零元素链对角占优矩阵所具有的个别性质对拟具非零元素链对角占优矩阵已经不再成立。
If A∈R^n×n is a L-matrix, and A isn＇t a diagonally dominant matrix, then some properties of the quasi diagonally dominant matrix with chain of non-zero elements were given. Examples illustrate that some special properties of the diagonally dominant matrix with chain of non- zero elements probably doesn＇t come into existence for quasi diagonally dominant matrix with chain of non-zero elements.
