摘要

对于任何简单连通无向图，我们都知道Kirchhoff和Kirchhoff乘次指标可以用拉普拉斯矩阵来计算。我们证明了加性度- kirchhoff指数也是如此，并给出了一个紧凑的Matlab程序，该程序以拉普拉斯矩阵作为唯一输入来计算所有三个kirchhoff指数。

Computing the Additive Degree-Kirchhoff Index with the Laplacian Matrix

For any simple connected undirected graph, it is well known that the Kirchhoff and multiplicative degree-Kirchhoff indices can be computed using the Laplacian matrix. We show that the same is true for the additive degree-Kirchhoff index and give a compact Matlab program that computes all three Kirchhoffian indices with the Laplacian matrix as the only input.
