PS: I apologize if this is not the right place to ask this kind of questions.

It is ok to ask this question. I wrote the first version of MB04PB 25 years ago. I did have a version for skew-Hamiltonians, that might be a lower-level support function or never made it into SLICOT. I will check my files, but this might take a few days.

Wow this is great, thank you very much!

Currently, SLICOT does not include a routine for computing the PVL form of a skew-Hamiltonian matrix. We do have one for skew-Hamiltonian/Hamiltonian pencils. An appropriate routine for item 1 above could be DSHPVB from HAPACK package. It might be possible to include its adaptation into SLICOT Library in the near future.
I don't know now an answer for item 2.

Sounds great! I had never heard of HAPACK before. A quick google search leads me to believe the project home page is https://www.tu-chemnitz.de/mathematik/industrie_technik/software/hapack.php?lang=en . The download links are all down though :-(

Maybe a project for your next visit? Best regards, Peter

Sure! Most HAPACK routines are already integrated into SLICOT. From the six routines you sent, two are already there, under the names MB01MD and MB01ND.
