Does gonum/matrix offer a way to calculate a [truncated SVD](https://en.wikipedia.org/wiki/Singular_value_decomposition#Reduced_SVDs)?
I'm working with a decomposed matrix that is juuuust at the bo…

Should we be considering optimal thresholding in truncated SVD (maybe as another dispatch for `truncated_svd`) ?
i think some DMD algorithms with noisy data try to employ these tricks. Paper [The Opt…

### Description
When using `cupyx.scipy.sparse.linalg.svds` on large (dense) matrices, the return values for the singular values are 0, and the U and V matrices are garbage.
### To Reproduce

So it took me ages to figure out the WHY, but I finally pinpointed some extremely weird behavior.
Namely, here's the simples code that reproduces the issue:
```php
$dataset = \Rubix\ML\Datasets…

truncated_svd appears to be unable to handle complex matrices (both with the method of truncation by explicit rank or tolerance). The following code which uses truncated_svd() via DMDSVD() fails.

Hello,
I integrated some data using Harmony back in 2022 (on Seurat V4), but I didn’t save the Seurat object at that time. When I needed to perform further analysis, I reran Harmony on the same dat…

If an SVD has degenerate singular values (multiple entries of S are exactly equal), the gradient pass will give `nan`.
This is because the [AD formula](https://arxiv.org/pdf/1909.02659.pdf) contain…

We will implement SVD, see for example http://stats.stackexchange.com/questions/159325/what-fast-algorithms-exist-for-computing-truncated-svd
