I posted 4 (four) releases of [PeriodicSystems](https://github.com/andreasvarga/PeriodicSystems.jl). Releases v0.1, v0.2 and v0.3 were based on SLICOT_jll_v5.7 and I switched to SLICOT_jll_v5.8 in Release v0.3.1. I extracted below from the history...

This issue has been partly resolved. The generated tarball for SLICOT_jll contains guarantedly valid libraries for Julia 1.7 (under Linux and Windows) and for Julia 1.8 (only under Linux). However,...

I think there are some notational confusions. > The only difference is my P is your docs Q, and vice versa... You probably meant R and Q, since P is...

I had a look to the [note applying LQ to economics](https://julia.quantecon.org/dynamic_programming/lqcontrol.html). Although I had no time to understand the details, but you should be careful to ensure that the conditions...

The trick with (R+R')/2 works just in the case you indicated, but it does not work when solving the Riccati equation. ``` julia> using LinearAlgebra, MatrixEquations julia> A = rand(2,2);...

Thanks a lot for these valuable comments. I am about to release version v2.0 of ME announcing also the transition to LM. My last effort was to improve the performance...

Regarding the `Adjoint` issue, at a certain moment I even removed the `adj` parameter from the definition of Lyapunov operators. This would also be possible for the inverse operators, where...

Thanks for the hints. Since in the meantime I made some modifications (I think the operator part was not effected), I wonder how to handle the PRs which you suggested....

Thanks.

I mentioned that for some reason, after initially removing `adj` from the definitions of `LyapunovMap` and `GeneralizedLyapunovMap`, I reintroduced it again. I think I intended to ensure a certain symmetry...
