非负矩阵转换为对角占优矩阵的一种简易方法

A Simple Method that Nonnegative Matrix is Converted to Diagonally Dominant Matrix

给出了一种非负矩阵快速转换为对角占优矩阵的简易方法。首先将非负矩阵转换为Hermite矩阵,然后利用Hermite矩阵的迹给出非负矩阵转换为对角占优矩阵的数值算法,最后对算例采用已有算法和本文算法进行比较。结果表明,本算法较已有算法更加易于实现。

In this article a simple calculation method is given that the nonnegative matrix into a diagonal dominant matrix,the numerical algorithm method is using trace of Hermite matrix when nonnegative matrix is transformed into Hennite matrix.Compared with the existing algorithms the example results show that the algorithm is easy to implement.
