I explained that the graph Laplacian of a simple path graph is the same as the matrix used in the Discrete Cosine Transform Type II (DCT-II).
More precisely, the eigenvectors of that graph Laplacian are the DCT-II
basis vectors. Subtle changes in the discrete boundary condition generates
matrices whose eigenvectors are DCT-I, III, IV, ... More about this interesting
relationship between the eigenvectors of discrete boundary value problems
and the various types of DCT and Discrete Sine Transform (DST) can be
found in
