Thank you for your reply. I'm glad to share the point. I will keep my asserts and use the NDEBUG just for my code. I leave this post open, so...

Thank you for your comment! Currently the interface is not supported, but it should be. I just started to import it so please wait a while!

I'm not a linear-algebra specialist too (sorry, my background is physics). But my library is based on so called "Krylov subspace method," whose characteristic is summarized in the 10th section...

@zhouyou-gu Thank you for waiting! I just released the exponentiator-included version `pylanczos==2.1.0`. Though no samples of the exponentiator interface are available for now, its [test code](https://github.com/mrcdr/pylanczos/blob/master/test/test_exponentiator.py) would be helpful.

@zhouyou-gu Thank you for your question. You don't have to configure the $m$ yourself. Lanczos exponention automatically determines it in the following iteration: 1. Calculate $\lbrace{ v, Av, Av^2, \cdots,...

@LUK4S-B Thank you for reporting this issue. I'm investigating it but still have not succeed to reproduce the problem even on numpy 2.x environment (both 2.0.2 and 2.2.1 latest). If...

@LUK4S-B Sorry for the late reply. I've tried your lanc_env.yml on miniforge, but the correct eigenvalues have been obtained. As you pointed out, pylanczos uses BLAS through numpy `dot` function...
