[bug#72320] [PATCH 0/2] Add python-slycot and python-control

[Vinicius Monego]

SLICOT is a Fortran 77 library for control computations. It was free software prior to version ~5.1 after which it became non-commercial, but seems to have been relicensed to bsd-3 in version ~5.8. It's in Debian main repo now and is the base for most Octave packages.

The build system for the fortran library is a little weird and the package would need some work. But I'm sending a package for Slycot (a Python wrapper) which forks it for a seamless integration, and then for python-control which is the main consumer of that wrapper.

Vinicius Monego (2):
  gnu: Add python-slycot.
  gnu: Add python-control.
