The Laplacian matrix is a matrix representation of a graph used to calculate properties such as the number of spanning trees and sparsest cut. It is related to the graph Fourier transform, which extends the discrete Fourier transform by substituting eigenvectors of the Laplacian matrix for complex sinusoids. The Laplacian matrix is most commonly used for edge-weighted graphs, but may require normalization if the weights are imbalanced.
