Thread: [python-control-discuss] windows no slycot

I am not sure if this is still the official mailing list for python-control
or not....

I am also resending this from what I think is my membership email for this
list.

I am getting ready to introduce state-space to an introductory (junior
level) dynamic systms and control course.  We really only need the basics
(probably just step and forced response).  Most of my students use windows
and most of them are not great with computers.  I just tried to do "pip
install slycot" in a windows virtual machine and received an error message
about the lack of fortran compiler.  I can work on that, but I am pretty
sure most of them can't handle MinGW.

So, my main question is this: what will and what will not work without
slycot for state-space simulations in python-control?

Thanks,

Ryan

Would it be an option to use anaconda? Then you can try the slycot I built
for anaconda just Monday (finally pulled this one off).

The problem is deeper than just mingw; the later lapack versions deprecated
some functions; you need lapack (at least that is the only option I have
seen binary versions for Windows for), and an updated Slycot to handle the
incompatibilities

Another option is Christoph Gohlke's python extension packages; that would
work for a regular Windows python http://www.lfd.uci.edu/~gohlke/pythonlibs/

Without slycot you are mainly limited in state-space work, and I think it
would be annoying to work around that in a course.

Success,

René

I tried

conda update conda
conda install slycot

and received a PackageNotFoundError

Do I need to somehow enable a super recent version of Anaconda?

The update supposedly put me at 4.3.27.
