The resizing algorithm used for the preview results in a jagged image (probably nearest neighbor aliasing). Please change it to Lanczos or at least (bi)cubic for a higher quality preview.

While bilinear filtering is fast, it is one of the least quality image filtering algorithms you could use. It matters more than you might expect, especially when trying to read text. I recommend you i…

It is pretty common to want to compute unitary matrix exponentials of the form $e^{iAt}b$ for Hermitian matrices $A$. It would be nice to have a method that takes advantage of $A$ being Hermitian he…

This issue is opened to state interest in a BlazeIterative implementation of the Arnoldi and (as a special case for Hermitian matrices) the Lanczos algorithm.

Currently when resizing the window, MilkyTracker seems to be using a linear scaling algorithm which causes text & the UI to be very blurry.
Instead of linear, nearest neighbor could be used instead.…

Right now it appears that reprojecting by interpolation is _only_ available as polynomial interpolation. Is that an intended restriction? For example, I would love to see Lanczos resampling (due to …

Current Spectral Clsutering algorihm is based on full distance matrix calculation and Lanczos algorithm for Eigenvalue decomposition. Whilst this provides accurate result at acceptable speed, the Nyst…

## 🚀 Feature
When working with large matrices, it's useful to access one or a handful of desired eigenpairs without computing the complete spectrum. PyTorch currently offers only `torch.lobpcg`, wh…

Hi, I'm trying to understand the math part of your algorithm. And I wonder which interpolation you use in order to upsample/downsample the image. I saw both LANCZOS and BILINEAR interpolation in [func…
