By accident, my program which is using `eigenvalues()` has become very good at constructing matrices which never converge during the search for their eigenvalues. Below is an example of such a matrix-…

On v0.1.25 on OSX, I get the following error when computing gradients from the following jit-compiled function.
```python

I realized that jax has expm, but doesn't have its inverse, logm. could you please add this feature? In TF, *the matrix logarithm using the Schur-Parlett algorithm. Details of the algorithm can be fou…

After tansition to PETSc 3.8.3 we have to definitely replace ilu preconditioner by icc because
of getting Inf in residual for very small conductivities (seems that diagonal scaling is not applied con…

We still don't have a gradient implementation for `Eig` (and a few other `aesara.linalg` `Op`s like https://github.com/aesara-devs/aesara/issues/836). [Here's](https://github.com/aesara-devs/aesara/p…

(1) Suppose T is a matrix. For T.transpose(), it is better to leave T unchanged and return transpose of T. But current version of Uni10 changes matrix T to its transpose.

Hi,
I’m trying to find the roots of a polynomial, and nalgebra has overall worked great.
Recently, I’ve found that my calculations hang on certain inputs, for which numpy immediately returns a v…
