Hi, is there a particular reason as to why you are setting the max(k) to be the number of clusters for SpectralClustering towards the end of the Verification Stage in the dave.py file?

Hi Yixuan,
I would like to appreciate your help for taking care of the issue I had with the EigenSymShiftSolver. I have tried to leverage these techniques to try and calculate the eigenvalues of a …

I'm trying to calculate first 3 eigenpairs of a test 2500x2500 matrix, and Spectra appears to give quite low precision. See [this code](https://pastebin.mozilla.org/9077857), accompanied by the [refer…

Usually we want to visualize not just one eigenvector but a set of them, so in this case, it is better to use a unified colormap for all of them.
A few points:
- all the text labels, if they are …

Hi, I used the dcca loss to train my dnn and got the following error message:
46 [D1, V1] = torch.symeig(SigmaHat11, eigenvectors=True)
47 [D2, V2] = torch.symeig(SigmaHat22, eigenvectors=True)
4…

If we find fast algorithm (for `O(n^3)` time) for transforming matrix to Jordan form, we can use this to fast rank calculation, eigenvalues and eigenvectors finding, and other useful things.

CuPy also has eigsh and it makes computation much faster, the code should be almost identical to what is alraedy there
```Python
if method == 'eigsh':
