In the IRAM eigensolver there is some quarantined code in `qrIteration` function that uses OMP. When activated it wall cause a x100 slowdown on the loop. The routine was prototyped in laptop code

I try to install it on OS win10(64bits), but I fail to run command "python setup.py install". Before installation, I install Cython with command "conda install Cython" as it required. If you have fixe…

I am confused by the computation of the GMRES residual, and the stopping test:
The variable `e_all_iter` is initialized as `r_norm` which is the actual norm of the initial residual (line 1273)
T…

This has been brought up on slack, but figured an issue would be good so all are aware of the issues.
I was mistaken in PR #499 for the behavior of 1D IMEX with GMRES. Currently the GMRES solver wi…

Many of the factorizations fall back on the default printing method for structs which is not that useful for the factorizations. I think the best `show` method is BunchKaufman, e.g.
```julia

Though it may be overkill to compute all of the theta for all lambdas and better to get a p…

I don't think going from the LHS to the RHS of this equation relies on the upper Hessenberg structure of H (so I don't think "Because H is upper Hessenberg" is necessary)

The purple block is titled "eigenvalues of block upper triangular" but then we write "Let H be an upper hessenberg matrix".
Shouldn't we be doing the proof for a matrix T, upper triangular? Yes H, …

I don't think we have an issue for this, and it seems to be consistently happening these days. E.g., https://build.julialang.org/#/builders/29/builds/4925/steps/2/logs/stdio:
