图的一些基本知识：关联矩阵、拉普拉斯矩阵 - CSDN博客
2020年3月8日 · 关联矩阵（Incidence Matrix） 关联矩阵是n×m的矩阵，n为顶点数量，m为边数量。 对于有向图，关联矩阵如下，其中若顶点在边的起点，则 dij=1；若顶点在边的终点，则 dij=-1；其他 dij=0。
Incidence matrix - Wikipedia
In mathematics, an incidence matrix is a logical matrix that shows the relationship between two classes of objects, usually called an incidence relation. If the first class is X and the second is Y , the matrix has one row for each element of X and one column for each mapping from X to Y .

2020年4月1日 · 无向图的两种主要表示方式是关联矩阵（Incidence Matrix）和邻接矩阵（Adjacency Matrix）。这两个矩阵都可以用来描述图的结构，但它们各有特点，适用于不同的操作和计算。 关联矩阵通常用于表示图中顶点和边的关系...
Incidence Matrix -- from Wolfram MathWorld
2024年11月21日 · The incidence matrix of a graph gives the (0,1)-matrix which has a row for each vertex and column for each edge, and (v,e)=1 iff vertex v is incident upon edge e (Skiena 1990, p. 135).
Graphs, networks, incidence matrices When we use linear algebra to understand physical systems, we often find more structure in the matrices and vectors than appears in the examples we make up in class. There are many applications of linear algebra; for example, chemists might use row reduction to get a clearer picture of what elements
MIT—线性代数笔记12 图、网络、关联矩阵 - 知乎
关联矩阵（Incidence matrices） 构造一个矩阵来表示图的内在含义，此矩阵称为关联矩阵，图中每个结点代表一列，每边代表一行。 则上图为54矩阵。
This section is about the incidence matrix of a graph—which tells how the n nodes are connectedby the m edges. Normally m > n, there are more edges than nodes.
Laplacian Matrices | An Introduction to Algebraic Graph Theory - Geneseo
We first define the incidence matrix of a graph. Let \(G=(V,E)\) be a graph where \(V=\{v_1,v_2,\ldots,v_n\}\) and \(E=\{e_1,e_2,\) \(\ldots,e_m\}\). The incidence matrix of \(G\) is the \(n\times m\) matrix \(\bs{M}\) such that \[ \bs{M}(i,j) = \begin{cases} 1, & \text{if \(v_i \in e_j\)}\\[2ex] 0, & \text{otherwise.}\end{cases} \]

The incidence matrix for the graph is a matrix representation of the graph. Each row represents an edge, and each column represents a node. For a given row, there is a —1 if the edge is leaving the node, and a 1 if the edge is entering the node, and a 0 otherwise. The incidence matrix for the graph above is: —1 1 0 0 —1 0 1 0 o —1 1 0 ...
