图的拉普拉斯矩阵
无向图如下所示:
邻接矩阵:
W = [ 0 3 2 1 3 0 5 0 2 5 0 3 1 0 3 0 ] \pmb{W}=\begin{bmatrix} 0 & 3 & 2 & 1 \\ 3 & 0 & 5 & 0 \\ 2 & 5 & 0 & 3 \\ 1 & 0 & 3 & 0 \\ \end{bmatrix} WW=⎣⎡0321305025031030⎦⎤
加权度矩阵:
D = [ 6 0 0 0 0 8 0 0 0 0 10 0 0 0 0 6 ] \pmb{D}=\begin{bmatrix} 6 & 0 & 0 & 0 \\ 0 & 8 & 0 & 0 \\ 0 & 0 & 10 & 0 \\ 0 & 0 & 0 & 6 \\ \end{bmatrix} DD=⎣⎡60000800001000006⎦⎤
拉普拉斯矩阵:
L = D − W = [ 6 − 3 − 2 − 1 − 3 8 5 0 − 2 − 5 10 − 3 − 1 0 − 3 6 ] \pmb{L}=\pmb{D}-\pmb{W}=\begin{bmatrix} 6 & -3 & -2 & -1 \\ -3 & 8 & 5 & 0 \\ -2 & -5 & 10 & -3 \\ -1 & 0 & -3 & 6 \\ \end{bmatrix} LL=DD−WW=⎣⎡6−3−2−1−38−50−2510−3−10−36⎦⎤
