Graph Signal Processing in Matlab
When I run gsp_demo_learn_graph_parameters.m, I am prompted some functions have not been found such as squareform_sp(), sum_squareform(), lin_map() and so on. 
I think the behavior on L141 in `gsp_graph_multiresolution.m` is wrong in the case when `largest_eigenvector(1)==0`, which now leads to filling `largest_eigenvector` with 0s as `sign(0)=0`. I suggest L141 being executed...
The current code throws "GSP_GRAPH_SPARSIFY: Epsilon out of required range" if `gsp_graph_multiresolution()` comes to the point that the current graph has three nodes. I think L175 in gsp_graph_multiresolution.m should be...
function appears to have many dependencies not included in the repo, including: normalize_data gabwin
The current implementation of the Erdos-Renyi graph seems to have an issue related to the generation of the adjacency matrix. In particular, the edge probability does not follow the input...
I found a bug that makes an incorrect gft result with a ring graph. ## Example Gfted one-hot vector's amplitude is constant. And its phase should be a line. However,...
In line 86 of the gsp_nn_hypergraph.m file, this line of code should be G.W (edge, ii)=sqrt(sum(w((1:k)+(ii-1)*k))), instead of G.W (edge, ii)=sqrt (sum (w (edge)).
