lanczos algorithm

[llvll0hsen]

Hello and thanks very doing this job. I am happy to see a project like this.have you implemented lanczos algorithm so far? I need to find the k largest eigenvalues of a dense matrix!

Thanks

Hi,

Yes, this can do that. In order to solve the generalised eigenvalue
problem, the system is transformed to a standard problem -- and this is
then solved using ARPACK. I spend some time discussing it in my thesis
which is available from my website.

If I get time, I will implement the standard eigenproblem solver, but I am
quite busy at work at the moment.

Regards

Thanks for reply. Which file is the last one that I can use for this
purpose? I need to wrap it for python but I'm not sure how and which source
file!
And is it referring to section 5.3.2 of your thesis?
Sorry I am a beginner!

Mohsen

Sorry, I have not been on GitHub for a while. Have you been able to make progress?
