Thanks for your nice toolbox.

Looks really useful. However, isomap seems to fail:
>> xy = isomap(dat);
??? Undefined command/function 'compute_nn_graph'.
Error in ==> isomap at 85
    D = compute_nn_graph(X,options);

Hi,

Thanks a lot for this toolbox. Is it possible to access the details (D) in a translation-invariant wavelet transform (TIWT)?
So that, for example, for a TIWT of depth 3:
signal = D1 + D2 + D3 + A3?

I had a look at the code but could not figure out how to do it.

Thanks a lot!

Very useful
compute_curvature will generate an error on line 75 ("dp = sum( normal(:,E(:,1)) .* normal(:,E(:,2)), 1 );") for SOME surfaces.
what's the solution of this bug
thanks
