The Graph Signal Processing toolbox is an easy to use matlab toolbox that performs a wide variety of operations on graphs, from simple ones like filtering to advanced ones like interpolation or graph learning. You can create all sorts of filterbanks including wavelets and Gabor. It is based on spectral graph theory and many of the features can scale to very large graphs.
