In sec2.3 you said graph wavelets can be obtained via Chebyshev polynomials instead of eigendecomposition of Laplacian matrix, but in your codes you still use eigendecomposition to calculate them, right?
Do you know where I can find the codes which use Chebyshev polynomials to obtain the wavelets bases?
