As I understand it, `es!` gives the Schur decomposition of a matrix by calling MKL [`gees`](https://software.intel.com/content/www/us/en/develop/documentation/mkl-developer-reference-c/top/lapack-rout…

**Description**
* DGEHRD reduces a general matrix A to upper Hessenberg form
* DHSEQR computes eigenvalues of a matrix of Hessenberg form and the Schur form
but in dget38.f, comments are only "…

Many tables contain bits like this:
```
- The table was first computed in:
{\sc M. Suzuki}, On a class of doubly transitive groups, {\em Ann. of
Math. \bf75} (1962), 105--145.
```
We shoul…

Some applications require an arbitrary sorting of eigenvalues in a Schur decomposition. Currently, `ordschur` supports re-ordering with a logical `select` vector that effectively groups the eigenvalu…

Hi,
I have been using the SymbolicWedderburn.jl package and have some questions regarding the decomposition and basis extraction.
Code:

## Problem
There's absolutely no need to have Schur multiplication in vector.multiply() deprecated- it's a useful tool for modders, it's especially useful for things like scaling. I don't see the n…

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…

We provide easy access to various group databases provided by GAP and various GAP packages.
I think we should provide some more credit to the authors of these databases in the manual. Possibly also…
