Is there a way to solve largest and smallest eigen values?

[decoherencer]

In scipy we can use LA/SM argument to get the either side of the spectrum, but is there way to use such option with this and Spectra-Eigen?

Hi, I've added which option so now you can use it like this:

pyspectra.eigsh(x, 16, backend="numpy", which="LA")

Example:
https://github.com/u1234x1234/pyspectra/blob/main/tests/test_eig.py#L22

You need to update package:

pip install git+https://github.com/u1234x1234/pyspectra.git@0.0.2

Please ask any questions
