Thanks for this information, Wayne. 

Out of curiosity, since you probably have it handy, can you send a list of the direct calls to slycot from python-control?  I’d be curious to know how many functions we call in total, since if we create a version of python-control that does not require slycot, we’ll have to find replacements for all of those functions.
